“Never miss a transaction again; meet Wallet Peep” When you’re active in the blockchain space, one of the biggest annoyances is keeping track of wallet activity in real time. You might receive tokens, get a transfer, or interact with a parachain, and never know when it happens until you check manually. And one of the most exciting aspects of Web3 development is connecting decentralized infrastructure with everyday tools people already use. @Wallet Peep comes in. It’s a lightweight, real-time monitoring service that watches wallet addresses on Polkadot parachains (paseo asset hub for now) and sends instant Telegram notifications whenever a transaction happens, allowing users to track wallet activities in real-time without leaving their chat app. In this tutorial, we’ll build Wallet Peep, a…  ( 13 min )

Abstract We introduce the Beta-Rho Orthogonality (BRO) score, a novel metric that quantifies the consistency between systematic risk exposure (beta) and correlation in cryptocurrency markets. Unlike traditional metrics that treat beta and correlation as separate measures, the BRO score reveals structural market relationships by examining their ratio. We demonstrate that this simple formulation serves as a multi-purpose analytical tool for: (1) detecting regime stationarity, (2) identifying tradeable structural relationships, (3) classifying predictability, and (4) constructing market-neutral portfolios. Our framework reveals four distinct behavioral regimes in crypto markets and provides a quantitative basis for distinguishing between manageable volatility and unmanageable chaos. Traditi…  ( 12 min )

When Kotlin was announced as an official language for Android in 2017, I didn’t rush to learn it. Java felt familiar, and I didn’t see the point in switching. Then one weekend, I tried rewriting a small project in Kotlin. Suddenly, everything was cleaner. No more endless boilerplate. Null safety built right in. Functional features that just worked. I didn’t just like Kotlin—I wanted to use it everywhere. That was my turning point. And I’ve seen the same story play out with countless devs. Kotlin starts as “the thing Android makes you use” and ends up becoming your favorite language. Fast forward to 2025: Kotlin is no longer just about Android. It’s powering full-stack apps with Ktor, showing up in Spring projects, and even being used in multi-platform codebases.

Microsoft’s decision to end support for Windows 10 isn’t just another software update—it’s a declaration: Your device is no longer yours to control. Millions of machines, still powerful and capable, are now deemed obsolete, not because they’ve broken down, but because a corporation decided their time was up. This isn’t just an ecological scandal; it’s a reminder that when you buy a computer, you’re not truly buying freedom. You’re entering a lease agreement, where the terms can change—or terminate—without your consent. What if you could use your hardware for as long as it lasts, without arbitrary restrictions or forced upgrades? That alternative exists, and it’s called Linux. Linux has come a long way since its early days as a niche system for developers. Today, it’s a polished, user-f…  ( 7 min )

I’m excited to announce that three of my UI designs were showcased during the Appian Community’s UX Design Lab | Mobile & Responsive Design livestream! 🎉 Seeing my work highlighted alongside so many creative and thoughtful submissions was an amazing experience. The session, hosted by Christine Danzi and Jennifer Higa, focused on the principles that make Appian applications not just functional — but intuitive, responsive, and user-friendly across all devices. Building for responsiveness goes beyond scaling layouts. Here are some of the core insights shared during the session that every Appian designer should keep in mind: Ensure that essential information remains visible and accessible on smaller screens without overwhelming the user. Design navigation structures that feel natural for mobile interactions — like bottom tabs or collapsible menus. Buttons, links, and interactive components should have ample spacing for easy tapping and accessibility. Use Appian’s dynamic layouts and conditional visibility to modify component behavior based on device size. Always test your designs on different screen widths to ensure consistent experiences across mobile, tablet, and desktop. Here’s a quick look at the responsive UI submissions that were featured in the livestream: A huge thanks to Christine Danzi and Jennifer Higa for hosting such an engaging session and providing valuable feedback on making Appian designs truly responsive. Events like these highlight the power of community learning — where every designer, developer, and contributor helps push the boundaries of what’s possible in low-code UX design.  ( 8 min )

Protect your web applications from automated content theft and AI data harvesting. In recent years, the rise of artificial intelligence has accelerated data collection across the internet. Many AI models rely on large-scale web scraping to feed their algorithms. Unfortunately, this often means that your website content — articles, APIs, or even private datasets — may be harvested without consent. These AI scrapers operate differently from ordinary bots. They mimic real browsers, rotate IPs from various countries, and simulate human-like behaviors to bypass traditional security tools. Some even execute JavaScript or use headless browsers such as Puppeteer or Playwright to collect dynamic content.

Optimistic Superposition: A Quantum Leap for AI? The dream of truly intelligent AI hinges on our ability to train complex models, a process currently bottlenecked by sheer computational cost. Imagine training a model not in weeks or months, but in hours. What if we could explore solution spaces previously deemed intractable? This is where "optimistic superposition" comes in. At its core, it's a novel algorithmic approach designed to handle complex problem-solving by strategically delaying computationally intensive calculations. Instead of immediately tackling every possible scenario, the algorithm makes optimistic assumptions, carries these assumptions as constraints, and only resolves them when absolutely necessary. This "wait-and-see" approach drastically reduces the initial computati…  ( 7 min )

GitHub Home I remember a few years ago, I was leading a team to develop a real-time stock ticker dashboard. 📈 Initially, everyone's enthusiasm was incredibly high. We were all excited to build a "live" application with our own hands. But soon, we found ourselves stuck in the mud. The tech stack we chose performed reasonably well for ordinary REST APIs, but as soon as WebSockets came into the picture, everything became unrecognizable. Our codebase split into two worlds: the "main application" that handled HTTP requests, and a "separate module" that handled WebSocket connections. Sharing state between these two worlds, like a user's login information, became a nightmare. We had to resort to some very clever (or rather, ugly) methods, like using Redis or a message queue to synchronize data. …  ( 10 min )

Beyond Binary RAG: Enhancing Decision-Making with Nuanced Risk Assessment The all-too-familiar Red, Amber, Green (RAG) system has become a staple in risk management and decision-making processes across various industries. However, an over-reliance on this binary approach can lead to oversimplification of complex issues, resulting in inadequate risk assessment and suboptimal decision-making. The Problem with Binary RAG The traditional RAG system categorizes risks into three distinct states: Red: High-risk or critical situations that require immediate attention. Green: Low-risk or stable situations that require minimal attention. Amber: Medium-risk or uncertain situations that require monitoring. While this system provides a basic framework for risk assessment, it often fails to capture the nuances of complex issues. The binary nature of RAG can lead to: False negatives: Critical risks being overlooked due to their classification as Amber. **... This post was originally shared as an AI/ML insight.

However, this may lead to a homogenized consumer experience, where people are shown the same ads repeatedly, reinforcing existing biases and limiting exposure to diverse perspectives. To mitigate this risk, AI-powered ad personalization can be designed to foster cultural diversity and creativity in advertising. Here are a few strategies: Diverse data sources: Implement data collection methods that actively seek out diverse perspectives, such as partnering with community organizations, social media groups, or cultural influencers. This ensures that the AI algorithm is exposed to a wide range of experiences and viewpoints. Inclusive modeling: Use AI models that p... This post was originally shared as an AI/ML insight.

O papel de equals() e hashCode() no Java Esses dois métodos vêm da classe Object, a base de todas as classes em Java. Eles determinam como o Java compara objetos e como eles são organizados em coleções baseadas em hash. equals(Object o) Define se dois objetos são considerados “iguais”. Por padrão (em Object), equals() compara referências (endereço na memória). Classes costumam sobrescrever para comparar conteúdo. class Cpu { String process; Pessoa(String process) { this.process = process; } @Override public boolean equals(Object o) { if (this == o) return true; if (!(o instanceof Pessoa)) Pessoa p = (Pessoa) o; return process.equals(p.process); } } hashCode() Retorna um número inteiro usado pelo algoritmo de hashing de coleções co…  ( 7 min )

By Mostafa Yousef Imagine this: you’re writing, editing, and formatting text — all flowing smoothly — when suddenly you have to grab your mouse just to make text bold or insert a link. That small break? It disrupts your rhythm. That’s why keyboard shortcuts are pure magic. They keep users in their creative flow, transforming ordinary typing into an effortless experience. And for developers working with editors like Froala, understanding how to create and customize shortcuts can take user productivity to the next level. This article will explore why users love shortcuts, and more importantly, how you can register and customize them in Froala Rich Text Editor to make your users feel truly intuitive and efficient.

Many challenges in AI products stem less from choosing frameworks and more from how user experience (UX) and architecture shape each other. I first noticed this while using ChatGPT to draft and maintain product requirement documents (PRDs) — reusing prompt variants, manually curating context, and constantly tweaking outputs to stay aligned. The workflow technically worked, but it felt brittle and overly manual. That experience raised a question: What might it take for an agentic workflow — a coordinated system of specialized LLM sub-agents orchestrated by code rather than a single prompt — to produce and maintain a complex artifact like a PRD without so much manual prompting, context oversight, and guesswork? More broadly, how could changes in architecture and UX design improve usability,…  ( 13 min )

🧠 Introduction: A New Way to Code Is Emerging For decades, coding has meant writing lines of code manually—debugging, optimizing, and maintaining them over time. But in 2025, a new wave of development is rapidly transforming that model: Vibe Coding. Vibe Coding is an AI-first programming paradigm where developers describe what they want, and intelligent agents handle much of the code generation. Instead of spending hours crafting functions line by line, engineers focus on high-level logic, problem framing, and iterative refinement. This isn’t just another “no-code” trend—it’s a fundamental shift in how we build software. At its core, Vibe Coding means: Developers express intent in natural language or structured prompts. AI agents generate, refactor, and optimize code automatically. The …  ( 8 min )

Or a chaotic pile of Notifiable, Taggable, SoftDeletable, and ThatThingWeNeededForTheMarketingReport?

And I... wasn't. After eight hours of solving problems, writing code, and staring at a screen, the last thing I wanted to do was more of the same. I'd force myself sometimes, opening my laptop with a sense of dread, only to produce low-quality code and feel even worse. I thought this meant I wasn't "passionate" enough.

In this project, we explored model evaluation metrics using a Lead Scoring dataset. The goal was to identify which factors most influence lead conversion and evaluate how well our model can predict them. Below are the key concepts and lessons learned throughout the assignment. A lead scoring model helps businesses identify which leads (potential customers) are most likely to convert. By assigning a score to each lead, sales teams can focus their efforts where it matters most — improving conversion rates and efficiency. In our dataset, the target variable (converted) indicates whether a lead converted (1) or not (0). The features included data such as: lead_score number_of_courses_viewed interaction_count annual_income Before modeling, we performed crucial preprocessing steps: Handling Miss…  ( 7 min )

Every great application begins with a simple, honest object. It does its job, it tells the truth, and it asks for little in return. It’s the UserService that fetches data, the Image that renders itself, the API that returns a response. But as our systems grow from humble scripts to sprawling architectures, this honesty becomes a liability. A naïve UserService can buckle under a million requests. A direct Image load can freeze a UI. A raw API call can be a gaping security hole. We need a guardian. A diplomat. An illusionist. We need the Proxy Pattern. This isn't just another Gang of Four entry.

Author: Samantha Laine King Last Updated: October 2025 This guide walks through adding a clean, accessible Dark Mode toggle to a React application using Tailwind CSS and localStorage. It covers setup, theme persistence, and best practices for accessibility. Tailwind provides built-in dark mode support. In your tailwind.config.js file, enable class mode so users can manually toggle it: // tailwind.config.js export default { darkMode: 'class', theme: { extend: {}, }, plugins: [], } This allows you to switch themes by adding or removing the dark class on the root element.

Imagine a world where your machine learning model automatically infers and implements them! What if we could leverage AI to build AI? The future of program synthesis might be closer than you think. Think of a reinforcement learning agent exploring an environment, learning optimal actions to maximize a reward. We can repurpose that learned behavior to define the state transitions of an automaton. Instead of rewarding specific actions, we reward reaching desired states or completing specific sequences of actions. The result is an automated process to build Finite State Machines that execute deterministic sequences. We essentially train an AI to become a DFA. The agent ex…  ( 7 min )

One of the things I love about Go is how practical it is when dealing with JSON.

Marshal and Unmarshal — for small or simple data These are the most common functions when your JSON fits comfortably in memory. ▶️ Go → JSON (Marshal) You convert a Go struct, map, or slice into JSON. type User struct { Name string `json:"name"` Email string `json:"email"` } user := User{"Hugo", "hugo@example.com"} data, err := json.Marshal(user) if err != nil { log.Fatal(err) } fmt.Println(string(data)) Output: {"name":"Hugo","email":"hugo@example.com"} Use Marshal when: You already have a Go object in memory.

Hey everyone, If you're a developer, you've probably been in this situation: a client sends you a database_dump.sql file, or you need to set up a local copy of a production database for testing. The usual process is tedious: Install the correct database server (Postgres? MySQL?) Create a new user and database Figure out the right command-line flags to import the .sql file Hope there are no version conflicts It's a frustrating 15-minute detour from the work you actually want to do. I got tired of this workflow, so I built a solution right into my app, FormPipeDB. It's a feature that allows you to take an entire SQL script—CREATE TABLE statements, INSERT INTO statements, and all—and turn it into a live, fully manageable database just by pasting it into a textbox. Here's how it works: Click "Import SQL..." Paste your entire SQL script. Click "Import Database." That's it. The app parses the script, creates all the tables, defines schemas, populates the data, and even builds foreign key relationships for you. You go from a static .sql file to a fully interactive database you can edit and query visually in less than a minute. This has been a game-changer for my workflow, especially for: Faster Prototyping: Instantly spin up a backend from an existing schema. Easy Debugging: Quickly load a snapshot of production data to test against. Client Work: Set up a database for a client project without any server configuration. The app is called FormPipeDB. I'm on a mission to get my first 100 paid users, so I'm running a $99 lifetime deal. I'd love for the dev.to community to check it out and give me honest feedback. You can try it at formpipedb.com.

Starting Out — and Feeling Lost I started my full stack software engineering career right out of college as a bright-eyed, bushy-tailed computer science graduate with terrible impostor syndrome. Who can relate? Between the firehose of onboarding information, a brand-new work environment, and an unfamiliar schedule, I felt completely overwhelmed. IBM ran large cohort-based onboarding workshops, and on top of that, I was meeting with different members of the team to learn as much as possible before jumping into real work. When the time came to tackle my first ticket, I was clueless.

You probably know what vibe coding is, even if you’ve never heard the term. It’s often pinned on junior devs who use AI to write code they barely understand—but real vibe coding is something else entirely. It’s what experienced developers do when we glance at a block of code and just know if it’ll work. We skim Stack Overflow, yank in half-understood libraries, and adapt stranger-solutions to weirdly specific problems. To new devs, it looks like wizardry. To us, it’s Tuesday. And here's the kicker: everyone treats AI-assisted coding like uncharted territory, as if we're all stumbling into the future hand-in-hand. But we’ve been collaborating with “…  ( 11 min )

Light Casters: So lets maek some different light sources, different types of light behave differently. Some lightsources are super far away but super bright whilst some are close but weaker. Directional Light: With this in mind theres no reason to calculate how each fragment compares the the light source position, since they are all coming from the same place essentially. So lets remove that from our light struct and change the lightDir calculations accordingly. And this should be the result. (Dont forget to set a direction for the light struct either!) Point Light: Faking fading light looks kind of fake without the proper mathematical equation, point lights tend to shine bright at a close position but quickly fall of as you get slightly further away, less of a gradual fade and more of…  ( 8 min )

When AWS experienced a global outage, it disrupted more than cloud services — it disrupted learning. As an ALX AWS Cloud Architect observer, I watched how the outage impacted Vocareum labs and brought cloud resilience principles to life. Here’s what it taught us about designing for failure, recovery, and real-world reliability. On October 20th, 2025, something strange happened — AWS went dark. At first, it felt like a typical hiccup. But soon, messages started pouring in across the ALX Cloud Architect community: “My Vocareum lab won’t load.” It wasn’t just one of us. It was everyone. The Ripple Effect The outage didn’t just stall projects — it became a live case study. Students running hands-on labs couldn’t deploy instances, monitor workloads, or test automation pipelines. For many, it was frustrating. For others, it was a wake-up call about the fragility of even the biggest systems we rely on. And that’s when it hit me: this is what cloud architecture is really about. Lessons Reinforced From the chaos came clarity. Every principle I’d studied in my ALX Cloud Architect track suddenly had real weight: High Availability isn’t just a term — it’s your safety net. Multi-Region Design matters because failures do happen. Monitoring and Alerts aren’t optional — they’re your early warning system. Fault Tolerance isn’t about preventing crashes; it’s about recovering fast when they happen. It was one of those moments where the theory became alive. The Way Forward After the dust settled, I found myself more inspired than frustrated. If AWS — the gold standard of reliability — can stumble, it only proves that no system is perfect. As cloud professionals in training, our mission isn’t to eliminate outages. And maybe next time an outage strikes, we’ll be the ones explaining why it happened — and how to prevent it from taking everything down.  ( 7 min )

It's relatively simple these days to spin up an OpenTelemetry demo and / or auto-instrument services with OpenTelemetry. That's fine - when it works - but it's when something breaks that perhaps you realise you don't quite understand what's going on under the covers. I've lost count of the number of times customers have reported "broken traces" to me as they flow through an uninstrumented tier, a load balancer or a queue. In the following video I show precisely how distributed tracing using OpenTelemetry is able to do what it does (for HTTP) by spinning up two Python FastAPI applications, instrumenting them using OpenTelemetry and demonstrating that the traces are "broken" in Jaeger. Then I solve the issue (hint: it's all about propagation). The code for all of this can be found here: https://github.com/agardnerIT/python-fastapi-requests-traceparent  ( 6 min )

As a developer, you’ve probably encountered various MySQL errors while working with databases. One common issue that can be quite frustrating is the ERROR 1130 (HY000): Host '192.168.7.7' is not allowed to connect to this MySQL server. This error typically occurs when trying to connect to a MySQL server from a remote machine using tools like TablePlus or MySQL Workbench. In this post, I’ll walk you through the steps to troubleshoot and resolve this connection error, so you can get back to developing without any interruptions. Let’s dive in! Understanding the ERROR 1130 The error ERROR 1130 (HY000): Host '192.168.7.7' is not allowed to connect to this MySQL server occurs when your MySQL server rejects connections from a remote host (in this case, 192.168.7.7).

You’ve spent weeks architecting the perfect AI agent. You’ve fine-tuned your prompts, selected a powerful Large Language Model (LLM), and are ready to connect it to the outside world. But then you hit the wall. One tool needs a REST API call structured this way, your database requires a different protocol, and your local file system feels a world away. Every new capability means another bespoke, brittle integration. You’re not building a streamlined agent; you’re managing a chaotic switchboard of incompatible plugs and sockets. This fragmentation is the silent friction slowing down the development of genuinely powerful, multi-talented AI systems. What if there was a universal standard, a common language for LLMs to talk to tools, data, and services? Enter the Model Context Protocol (MCP). …  ( 12 min )

Memory leaks are a common issue in Node.js applications, especially when running inside containerized environments like Kubernetes. A memory leak occurs when an application keeps allocating memory without releasing it, leading to increased memory usage and eventually to container restarts or crashes. Here’s a typical graph of what a memory leak looks like: memory usage constantly increasing over time until the pod is restarted. Unclosed Redis or database connections Global variables accumulating data Event listeners that are never removed In short: memory leaks happen more often than you think, especially in complex services. And the tricky part? You won’t always see them in your local environment, since production traffic and timeouts behave differently. In our case, for example, the lea…  ( 8 min )

React Component GPT: We need a GPT that understands our React components, knows our CSS variables, and can spit out code that's ready to use. This isn't about general knowledge; it's about our knowledge. The standard GPT knowledge upload is fine for broad docs, but for precise component generation, we need control. That's where Actions come in. Our design system lives in zeroheight. Our CSS variables are in a .css file. Our React components are in .jsx files. These are all discrete sources of truth. A generic LLM has no idea how they connect. If someone asks for a "primary button," it might give generic HTML, not our Button component with --color-brand-primary. Unacceptable. We build an API. This API becomes our "knowledge retrieval service." The GPT uses Actions to call this API when it…  ( 7 min )

When I started building my own startup, I had one goal — to turn ideas into something real fast enough to test if people even cared. That’s the truth most founders learn the hard way: it’s not about building a perfect product, it’s about learning fast and adapting even faster. In 2025, speed is everything. The tools are smarter, AI is everywhere, and customers expect products to work right out of the gate. But despite all that, the fundamentals haven’t changed — execution, clarity, and discipline still win. Here’s what I’ve learned while building and launching MVPs (Minimum Viable Products) for startups and for my own company, EulerHive.

How we evolved from Git chaos to a workflow that actually works for agency client projects "Which branch has the latest changes?" It was 4 PM on a Friday, and we had a client demo scheduled for Monday. Three developers had been working on different features, and nobody was quite sure which branch contained what. We had feature/new-dashboard, client-feedback-updates, johns-branch, fix-urgent-bug, and staging all containing different versions of the codebase. Merging everything took the entire weekend. The demo Monday morning included two features the client had specifically asked us not to include yet, was missing one they'd approved, and had a critical bug we thought we'd fixed in a different branch. That disaster forced us to acknowledge that our Git workflow, or lack thereof, was causin…  ( 14 min )

Yesterday, the internet had a bad day — and so did millions of users and businesses around the world. On October 20, 2025, Amazon Web Services (AWS) experienced a major outage that disrupted everything from streaming platforms and smart homes to enterprise apps and financial services. This wasn’t just another technical hiccup. It was a stark reminder of how fragile the modern internet can be when so much of it depends on a handful of companies. The issue began in the US-EAST-1 region — AWS’s most popular and densely used zone. According to Reuters, a problem with internal load balancing and DNS resolution cascaded through multiple AWS services. The result: apps and websites couldn’t connect to the servers they relied on. Among those affected were McDonald’s, Apple Music, Microsoft 365, Al…  ( 7 min )

I want to share with you a powerful AWS serverless pattern that uses two of my favourite AWS services: AppSync Events and EventBridge Pipes. Using these services we can combine the power of event-driven architecture with realtime user notifications.

Il giornalismo trattato come scienza comincia dalla definizione delle variabili: evento, contesto, attori, effetti. Senza un lessico condiviso, il racconto diventa aneddoto. Il taccuino è un laboratorio portatile: si formulano ipotesi, si cercano confutazioni, si annotano incertezze con la stessa dignità dei fatti accertati. Il campionamento delle fonti segue criteri espliciti: indipendenza, prossimità ai dati primari, competenza. Una testimonianza singola pesa come un indizio, non come una prova. La regola è triangolare: documento, voce diretta, osservazione sul campo. Quando due elementi concordano e uno diverge, si indaga il perché del disallineamento. La misurazione non è solo numeri. Anche le parole hanno metriche: frequenza, coerenza temporale, compatibilità causale. Le citazioni si trattano come segnali: si eliminano i “rumori” (opinioni non verificate, interessi nascosti), si puliscono i bias, si indicano i margini d’errore. Un buon pezzo espone non solo cosa si sa, ma quanto e con quale confidenza. L’etica è il protocollo di sicurezza. Proteggere le fonti equivale a proteggere l’apparato sperimentale: senza fiducia, i dati non arrivano. La proporzionalità guida ogni scelta: mostrare un nome, un volto, un dettaglio privato richiede di dimostrare l’utilità pubblica superiore al danno possibile. La trasparenza metodologica è parte del risultato. La pubblicazione chiude il ciclo e apre il successivo. Rendere disponibili i materiali, linkare gli archivi, spiegare passo per passo come si è arrivati alle conclusioni permette la replicazione da parte della comunità. Così il giornalismo non si limita a “informare”: costruisce una base cumulativa su cui altri possono testare, correggere e avanzare.  ( 6 min )

Introduction: The Hidden Cost of Poor Incident Follow-Up How did this happen again? Didn't we prepare for this? No engineering leader wants this message—especially after months of careful planning. Yet there we were: during our peak traffic spike, a critical customer-facing service slowed to a crawl, badly impacting customers exactly as we had seen before. Senior executives had to spend days personally reassuring frustrated customers, promising once again to finally address the underlying issues. The painful truth was that our infrastructure was outdated and architecture desperately needed refactoring. Instead, we’d spent months scaling hardware, applying patches, and tackling easy fixes—everything except solving the core problem. Our team knew what was needed, but the organization neve…  ( 12 min )

What is everyone using!? The Diagram Tool Wars in the LLM Era Our Shared Frustration Greetings from Japan. Let's be honest. Every time I draw a diagram with Mermaid, I secretly pray to the coding gods, "Please, don't let the lines cross." It's no longer a technical challenge, but more like a game of chance. To put an end to this personal ordeal and find a better, data-driven solution, let's start a discussion. When documenting, what are people honestly using to draw diagrams!? Mermaid? PlantUML? Or are you still firing up draw.io in the end? Come on, tell me honestly! Tell me!! The common challenge developers face is always the trade-off between "ease of use" and "freedom of expression."

Imagine this — you create a beautiful piece of software on your system. It runs perfectly, fast and smooth. But the moment someone else tries to run it on their machine, it breaks. One system says “library not found”, another says “version mismatch”. The software worked fine in your world, but not in theirs. This was the never-ending loop of frustration every developer once faced. In the early stages of software development, everything lived directly on the physical computer. Each machine had its own setup — operating system, installed software, dependency versions. That meant if you deployed the same code on ten different servers, it could behave ten different ways. To tackle this inconsistency, Virtual Machines (VMs) were introduced. A Virtual Machine acted like a computer inside another…  ( 8 min )

Every programmer has encountered it — that one phrase whispered with a mix of fear, awe, and exhaustion: “That part of the code is… legacy.” Legacy code — the mysterious beast that has survived through years of updates, countless developers, missing documentation, and still powers your company’s core systems.

The “crap” part defines its internal quality (or lack thereof): Logic tangled like spaghetti: Hundreds or even thousands of lines in a single function, seven layers of if-else, and mysterious conditions that even the original author no longer understands.

Ever been worried about bots scraping your data, attackers brute-forcing logins, or your platform getting hit with a sudden spike in expensive operations? Without proper protection, a simple DDoS attack or bot script can cost you time, resources, and even thousands in third-party service fees (like SMS). Let me show you how to implement a thread-safe, high-performance rate limiter using Python, FastAPI, and Redis. Rate Limiting: Allow only X requests per Y seconds per user. For example: 100 requests per 60 seconds Fast: Stores data in memory, allowing for near-instantaneous read/write operations critical for low-latency APIs. Automatic Windowing: The EXPIRE command lets us define a "time window" (e.g., 60 seconds) after which the counter is automatically cleared, saving manual cleanup code…  ( 7 min )

In this tutorial, we'll walk through the creation of a simple physics-based doll using the Pixalo game engine. We will cover each part of the code step by step, explaining its purpose and functionality. 1. Importing Pixalo First, we need to import the Pixalo engine into our project. This can be done through a CDN link. Here's how we do it: import Pixalo from 'https://cdn.jsdelivr.net/gh/pixalo/pixalo@master/dist/pixalo.esm.js'; Next, we'll create a new instance of the Pixalo engine and set up our game canvas. We define the dimensions and background color, as well as the physics properties (in this case, gravity). const game = new Pixalo('#canvas', { width: window.innerWidth, height: window.innerHeight, background: '#031C1B', physics: { gravity: { y: 800 } } …  ( 9 min )

Why Cursor over Claude Code? Code-generation diffs are easier to review and roll back (the checkout system is great). You can test and use other models for different tasks (o3 for complex tasks, gemini-2.5-pro for creativity, grok-code-fast-1 for quick tasks, etc.).* Good IDE integration (e.g., accept/reject actions work great across the UI). *That said, I’m only using claude-4.5-sonnet since its launch. Use .cursorrules or similar to enforce behavior. For example: - Always use the project’s Tailwind colors. - Always use named exports with object parameters: `sum({ a, b })` instead of `sum(a, b)`. - Use "pnpm" instead of "npm" for all package-management commands. - Use the "use client" directive when using client-side state like useState, useEffect, etc. - Don’t modify package.json dep…  ( 7 min )

Introduction As businesses modernize their IT infrastructure, hosting web applications in the cloud has become a key strategy for improving scalability, reliability, and cost efficiency. Many organizations still rely on on-premises servers to host their company websites, but these setups often come with high maintenance costs, limited scalability, and hardware refresh challenges. To eliminate the burden of physical infrastructure, companies are increasingly adopting Azure App Service a fully managed Platform as a Service (PaaS) solution for hosting web applications built on popular runtime stacks like .NET, Java, Python, Node.js, and PHP.

The cloud promised to simplify everything — agility, lower costs, and effortless global deployments in just minutes. But… what about security? Securing cloud environments has become far more complex than most expected, while opening a door for attackers is easier than ever. By its very nature, the cloud allows both employees and cybercriminals to access systems from anywhere in the world — as long as they have the right credentials and no additional controls are in place to stop them. This accessibility, one of the model’s greatest strengths, is also its Achilles’ heel. In this article, we’ll debunk some of the most dangerous myths about cloud security. The cloud isn’t exactly new — it’s been around for nearly 20 years (if we count from the launch of AWS). Yet, several myths continue to sh…  ( 7 min )

After a few comfortable years in the same flat, I found myself back in the nightmare that is the German housing market. Hundreds of applicants for one place, five-minute viewings, and forms that look like they were faxed straight from 1998. The worst part wasn’t even the competition - it was the Mieterselbstauskunft. It's a form that most landlords want. And you're gonna need it multiple times, thats just the housing market here. After hours of searching, it seems that there is just no real good way to fill it. To combat it, I built a small iOS app that lets you fill out and sign your rental self-disclosure digitally. Native form inputs, built-in signature with a handwriting-look, and a clean final PDF you can reuse in seconds. I know that developing it cost 20 times more time than I will save by using it. But if a handful of people start using it too, it will be a net positiv on the human-time bottom-line. If you’re curious, the app’s here: https://selbo-app.de/  ( 6 min )

This is a submission for the Auth0 for AI Agents Challenge I built Snape, an AI agent that can manage your GitHub account — from listing repositories to performing actions like checking issues or commits — all through natural language prompts. Instead of typing out API calls or clicking through dashboards, users can simply say things like: “List my private repos from the Snape workspace” “Show me the open issues in my nextjs project” Snape will understand your intent, securely fetch the data using your GitHub access, and respond conversationally. The AI is workspace-aware — meaning different teams or users can manage their own connected GitHub accounts separately, with proper permission checks.

Fine-Tuning LLMs: Avoiding Catastrophic Forgetting with a "Warm-Up" Approach When adapting pre-trained Large Language Models (LLMs) to specific tasks, a common challenge arises: catastrophic forgetting. This phenomenon occurs when the model's performance on the original task suffers significantly after fine-tuning on a new task. To mitigate this issue, we recommend using a "warm-up" approach with smaller learning rates. Why "Warm-Up"? The "warm-up" phase involves gradually increasing the learning rate from an initial small value to a larger one. This approach helps the model to: Stabilize the pre-trained weights: By starting with a small learning rate, you prevent the model from making drastic changes to its pre-trained weights, which are essential for its original performance. Adapt to the new task: As the learning rate increases, the model can learn to incorporate new knowledge without forgetting its original capabilities. Prevent overfitting: The ...

Model Overinterpretation: A Hidden Pitfall in XAI In the pursuit of transparency and accountability in AI decision-making, Explainable Artificial Intelligence (XAI) techniques have become increasingly popular. Methods like SHAP (SHapley Additive exPlanations) values and LIME (Local Interpretable Model-agnostic Explanations) provide valuable insights into an AI model's decisions by attributing importance to individual features. However, a common pitfall lies in overinterpreting these results, which can lead to oversimplification and misrepresentation of complex interactions between features. When using SHAP values or LIME, it's essential to remember that these methods: Simplify complex relationships: By focusing on individual feature contributions, these methods might overlook intricate dependencies between features. For instance, a model may predict a patient's likelihood of developing a disease based on a combination of genetic markers, environmental factors, and ...

Let’s be honest: how much of your day is spent re-typing the same long commands? How often do you run one command just to find an ID, then copy-paste it into the next one? Every docker ps | grep my-app, kubectl get pods -n prod, or manual copy-paste is a small interruption that kills your momentum and pulls you out of the zone. What if your shell could anticipate your next step? What if it could turn those multi-command workflows into a single, interactive action? That’s why I built IntelliShell, an open-source CLI tool that acts as a smart copilot for your terminal.

Agents are the New Developer 80% of Claude Code was written by AI. More than a quarter of all new code at Google was generated by AI one year ago. It’s safe to say that in the next 12 months, the majority of all new code will be written by AI. Agents don’t behave like humans. They behave in new ways. Software development tools need to evolve. Agents need a new kind of database made for how they work. But what would a database for agents look like? At Tiger, we’ve obsessed over databases for the past 10 years.

JVM - (Java Virtual Machine). Java Virtual Machine is the foundation of Java programming language and ensures the program's Java source code will be platform-agnostic. It's used to run Java bytecode. JVM is included in both JDK and JRE, and Java programs won't run without it. JVM is responsible for converting bytecode to machine-specific code(binary) and is necessary in both JDK and JRE. It is platform-dependent and performs many functions, including memory management and security. TheJVM is platform-dependent, meaning a specific JVM implementation exists for each operating system (e.g., Windows, macOS, Linux). JDK - (Java Development Kit) Java Development Kit is a software development environment that includes JRE and development tools. It's used to create Java applications and applets. JDK includes tools like a compiler, debugger, and documentation generator. JDK contains all the tools that are required to compile, debug, and run a program developed using the Java platform. These development tools include the Java compiler (javac), debugger, Javadoc tool, and other utilities necessary for writing, compiling, and debugging Java programs. JDK is essential for Java developers who need to create and compile Java code. JRE - (Java Runtime Environment) Java Runtime Environment is a set of software tools that provides a runtime environment for running other software. It's used to run Java applications. JRE contains class libraries, supporting files, and the JVM. The JRE is designed for users who only need to run Java applications and do not require development tools. For example, we write a code called first. First.java(our code) --> First.class (byte code) --> Binary code. In single line Example: JVM: is the engine that executes Java bytecode, ensuring platform independence. JRE: is the environment required to run Java applications, containing the JVM and necessary libraries.

GitHub Home I still vividly remember that Friday midnight. I, a man in my forties who should have been at home enjoying the weekend, was instead in a cold server room, the hum of fans buzzing in my ears, and a stream of error logs scrolling endlessly on the terminal before me. What was supposed to be a "simple" version update had turned into a disaster. The service wouldn't start, the rollback script failed, and on the other end of the phone was the furious roar of a client. At that moment, staring at the screen, I had only one thought: "There has to be a better way." We old-timers grew up in an era when the term "maintenance window" was a fact of life. We were used to pausing services in the dead of night, replacing files, and then praying that everything would go smoothly. Deployment was…  ( 12 min )

Web3 was supposed to be a revolution. A decentralized web, owned by its users, powered by transparency, trust, and autonomy. The vision was beautiful: an internet where middlemen disappear, creators earn directly, and users regain control of their data and digital lives. But behind the idealism lies a harder truth. Web3 is not free. It comes with hidden costs that affect developers, designers, users, and the ecosystem as a whole. Let’s unpack the real price of building the future. ⚙️ 1.

A few weeks ago, I decided to take my React.js learning seriously. I had gone through tutorials, built small components, and experimented with hooks — but I wanted something real, something that could represent me as a developer. That’s when I decided: I’m going to build my own portfolio website. At first, it felt overwhelming. How should I structure the components? How do I manage state efficiently? What about responsive design? Each challenge felt like a mini-battle. 😅 As I started building: Components and Reusability: Breaking the UI into smaller, reusable parts made the code cleaner and easier to maintain. State & Props: Handling data flow taught me the nuances of React, and how small mistakes can ripple through the app. UI & Responsiveness: Making the portfolio look good on different devices pushed me to improve my CSS and layout skills. Debugging & Patience: There were moments I got stuck for hours on useEffect and conditional rendering — but solving them gave me huge satisfaction. By the end, I had a portfolio that wasn’t just a collection of projects — it was a reflection of my growth, persistence, and learning journey. 💡 Key Takeaways: Building something personal teaches more than tutorials ever can. Mistakes aren’t failures — they’re lessons in disguise. Seeing your ideas come to life is incredibly motivating. Next, I plan to connect this React portfolio with a Django backend, making it dynamic and interactive. 🔗 Check it out: https://thiyagu26v.github.io/myreactportfolio/ https://github.com/thiyagu26v/myreactportfolio ReactJS #FrontendDevelopment #WebDevelopment #Portfolio #LearningJourney #FullStackDeveloper #Django #DeveloperLife #LearningByDoing  ( 6 min )

AirBnB, Slack, SnapChat par terre ! Les médias se sont fait l'écho (par exemple ici Le Monde avec l'AFP) d'un incident majeur touchant l'infrastructure d'AWS, parlant de « panne mondiale ». Le terme est-il approprié ? Nb : il ne s'agit pas de "défendre" AWS, ni de nier l'ampleur de l'incident, mais de donner l'opportunité aux moins "tech" de comprendre ce qui se cache derrière. L'un de mes clients a toute son infrastructure sur les datacenters d'AWS en France (on parle de "région" de Paris, ou eu-west-3). Il n'a juste eu aucun impact de l'incident. Business as usual.

A Developer’s Perspective on Smarter Project Validation Before you build, deploy, or scale anything—whether it’s a SaaS platform, an app, or a data-driven startup—you need to answer one question: As developers, we’re usually eager to jump straight into writing code or setting up cloud infrastructure. But feasibility analysis isn’t just a business formality—it’s what saves us from building the wrong thing too early. Let’s explore the top tools and frameworks that can help simplify your feasibility analysis process—especially for developers who want to validate ideas efficiently before writing a single line of code. Feasibility.pro — For Structured Feasibility Studies Feasibility.pro is one of the most comprehensive platforms focused entirely on feasibility studies. It helps break down y…  ( 7 min )

How to Learn System Design: Real Insights and Examples System design is not just theory it's the art of building scalable, reliable systems. Here’s a practical guide based on real experience and observation. If you want to understand system design, start by mastering databases and how to scale them. This teaches you: Horizontal vs Vertical scaling Replication Sharding Caching Consistency Indexes Availability Failover Why? These patterns repeat everywhere. If you get comfortable with database scaling, you’ve learned 70% of system design. Example: Suppose you have a user table with millions of records. Sharding: Split users by region or ID range across multiple databases. Replication: Use a master database for writes and multiple slaves for reads. Caching: Store frequently accessed use…  ( 7 min )

I'm on quite a few different Discord servers, and one of them has a 3D printing channel with a catalog of STLs. Initially, it was just a bunch of posts in a specific channel that got pinned. The problem? Those pinned posts were constantly outdated and needed manual updates from moderators or whoever originally posted them. Pretty tedious and annoying to keep bugging them. One of the community members had a brilliant idea: why not use Raindrop.io? We could make it a collaborative catalog that willing contributors could help maintain. It worked great! The catalog grew into something really useful... but there was one catch. Every time someone wanted to search for an STL file, they had to leave Discord and open Raindrop in their browser. So I thought, "Why not bring the search functionality d…  ( 17 min )

When you build modern AI systems — from recommendation engines to RAG-powered chatbots — there’s one hidden hero that makes it all work: vector databases. Among the many options available today (like Pinecone, Weaviate, or Chroma), Qdrant has emerged as one of the most powerful, production-ready, and developer-friendly solutions out there. In this post, we’ll dive into: What Qdrant is and how it works, Why it’s so useful for real-world production AI, How it fits into the vector database ecosystem, And how you can get started quickly.

I've been diving deep into the world of AI and cloud computing lately, and let me tell you, it’s a wild ride! Imagine my surprise when I stumbled upon Alibaba Cloud's recent announcement that they’ve managed to cut Nvidia AI GPU usage by a whopping 82% with a new pooling system. That’s not just a minor tweak—it’s a game-changer! Ever wondered how such a drastic reduction could impact the industry? Well, grab a cup of coffee, and let’s unpack this together. When I first heard about GPU pooling, my mind raced back to my early days as a developer when I struggled to understand the concept of resource management in cloud environments. Imagine a crowded café where everyone wants to use the same limited number of power outlets. That’s kind of how GPUs work in traditional setups. You need them, b…  ( 8 min )

It's been encouraging to see my browser extension, Bookmark Dashboard, has now reached 700+ users (500+ on Chrome, 200+ on Edge). Recently I have made a bunch of optimizations, and today I want to share how I implemented the drag-and-drop feature for bookmarks. Usually the browser's native bookmark manager already supports dragging and dropping bookmarks or folders to move them around. However, this convenient feature was missing in Bookmark Dashboard until now. Previously, moving bookmarks or folders mainly involved opening a modal, selecting the target location, and finally clicking a confirmation button. If I just want to drop a bookmark into a folder right next to it, there’s no denying that drag-and-drop is the more intuitive and convenient way. To make Bookmark Dashboard embody all …  ( 9 min )

Als je wel eens een 3D-design hebt gemaakt, herken je dit vast: je ontwerpt iets zorgvuldig, print het uit... en ontdekt dan dat het toch niet helemaal past of er niet uitziet zoals je had verwacht. Vaak kom je daar pas achter na de eerste of tweede print, wat natuurlijk tijd en materiaal kost. Ik liep tegen precies hetzelfde probleem aan. Daarom heb ik een simpel programma geschreven dat een live camerabeeld combineert met een .stl-bestand, zodat je met Augmented Reality direct kunt zien hoe je ontwerp in de echte wereld staat. Zo voorkom je onnodige prints en krijg je sneller een goed beeld van het eindresultaat. Het idee is simpel: je streamt de camera van je telefoon naar je laptop, laat die live beelden uitlezen in een Python-programma, en laadt daaroverheen een 3D-render van je ontwe…  ( 11 min )

Since I came to France six months ago, I have made a lot of progress with the French language. What started as nearly incomprehensible stuttering are now full phrases with rich vocabulary and even one little joke here and there. I've made picking up French my personal project, and it brings a lot of joy in my life. Understanding people in more and more contexts is enriching and helps with the struggles every expat experiences being far from home. I recently stumbled across a talk by Chris Lonsdale from nearly ten years ago, where he talks about his experience learning languages. I highly recommend watching it if you haven't already. It resonated so well with me that it inspired me to write this blog post. He claims anybody can be fluent in a new language in six months. It sounds crazy, but…  ( 12 min )

Async/await is a major source of confusion in JavaScript. People tend just to add and remove the async and await keywords until the code works (or seems to work). In this article, I want to explain what async/await actually means by developing the concept from vanilla, synchronous JavaScript to asynchronous JavaScript with the async/await syntax sugar. It is my personal take on the subject. I hope some will find it interesting. Disclaimer: I use Node.js as an example of a JavaScript runtime in this article. However, what's discussed also applies to other runtimes like web browser JS engines. All these environments follow similar architectures.

TL;DR Before writing a single line of code, take one day to model your data. This simple discipline turns chaos into clarity, prevents endless refactors, and keeps your logic aligned with real business needs. Modeling isn’t bureaucracy — it’s efficient laziness: thinking once, well, so you never have to redo the same work. Before diving in, a quick nod to a great post I read recently: These 5 Coding Habits Separate a Good Developer from a Great One. It starts with a truth I fully agree with: great developers think “why” before “how.” That mindset is exactly what this story is about — modeling before coding. There are two types of developers: those who open their editor and create tables as needs arise, and those who first pull out paper and pencil. I belong to the second category. Not …  ( 11 min )

The book Docker and Kubernetes Security is finally here, after two years, 170 git commits, and countless hours of writing, editing, and reviewing. It's available on DockerSecurity.io. You can get the eBook, paperback, or a signed copy (that I'll sign and send to you). 🐳🔐 So, why did I write this book? I became a Docker Captain in March 2023. That probably put me on this publisher's radar. Shortly after that, a major UK publisher reached out to me, asking if I would be interested in writing a book on Docker Security. At first, I was hesitant. Writing a book is a huge commitment, and I wasn't sure if I had enough expertise in Docker Security. The publisher was very persuasive, though, and I eventually agreed to write a proposal. Here is my monthly tweet about writing a proposal in July 202…  ( 9 min )

This is the story of "SaaSify," my journey from a simple idea to a complete, sellable product on Gumroad. Chapter 1: The Idea and Design My design process started with research on sites like Lapa Ninja and Awwwards.

Space is Luxury: A clean, uncluttered layout feels professional. I decided on a dark blue background to evoke trust and stability, and a purple-to-blue gradient for accents.

The Problem with Modern Framework Overhead Most modern web frameworks ship with Virtual DOM implementations that add significant bundle size before you write a single line of application code. For small to medium-sized web applications, this overhead often feels unnecessary. After working on multiple projects and consistently running into this issue, I decided to explore an alternative approach. Rynex is a zero-configuration TypeScript framework for building reactive web applications without Virtual DOM. Instead of maintaining a virtual representation and performing diff operations, Rynex uses direct DOM manipulation combined with proxy-based reactivity to achieve fast, efficient updates. The core principle is simple: when state changes, Rynex updates only the affected DOM nodes directly…  ( 8 min )

Introduction to Bert : Part One Have you ever wondered how Siri understands your voice, or how Google Translate can switch between English and Spanish in seconds? Behind these everyday miracles lies the fascinating field of Natural Language Processing (NLP) — the bridge between human language and machines. In this post, we’ll explore how NLP evolved, why it was challenging, and how BERT (Bidirectional Encoder Representations from Transformers) changed the game forever. In simple terms, NLP means teaching computers to understand and generate human language — just like how we talk or write.

On July 26, 2025, SendGrid ended its free plan. Instead of paying $20 per month to SendGrid, I built a SendGrid alternative called WhautoMail. It connects to your own AWS SES or Mailgun account, plugs into Stripe and Chargebee events, and costs only $1 per month. No vendor lock-in. No surprise upgrades. When SendGrid killed the free plan they gave only two choices: Upgrade to $20 per month Move to another provider and rewrite all integrations As a bootstrapped founder, both options were bad. And this is common with VC-backed email tools. They offer big free tiers to acquire users, and once you are integrated and dependent, they change pricing or kill free plans. This is not accidental. This is the business model. The real problem is not SendGrid. The problem is vendor lock-in. I bui…  ( 7 min )

1. What is a Router: A router in backend frameworks (like Express.js) defines how your app responds to client requests (GET, POST, PUT, DELETE) on specific URLs. Example concept: Client → /api/users Purpose: Organizes endpoints. A controller contains the logic for handling requests. Purpose: Keep logic separate from routes. Router file defines the endpoint: router.get('/users', getAllUsers); Controller file defines the function: const getAllUsers = (req, res) => { // logic to get users }; When /users is requested, router calls the controller. project/ │ ├── routes/ │ └── userRoutes.js │ ├── controllers/ │ └── userController.js │ userRoutes.js import express from 'express'; import { getAllUsers, createUser } from '../controllers/userController.js'; const router = express.Router(); router.get('/', getAllUsers); router.post('/', createUser); export default router; userController.js export const getAllUsers = (req, res) => { try { res.status(200).json({ message: "Users fetched successfully" }); } catch (error) { res.status(500).json({ message: "Error fetching users" }); } }; app.js import express from 'express'; import userRoutes from './routes/userRoutes.js'; const app = express(); app.use(express.json()); app.use('/api/users', userRoutes); app.listen(3000); Console Logging Log req.body, req.params, req.query to verify data. Example: console.log("User ID:", req.params.id); Use Debuggers VS Code: Add breakpoints in controller files. Run app in debug mode (node --inspect app.js). Error Middleware app.use((err, req, res, next) => { console.error("Error:", err.message); res.status(500).json({ message: "Something went wrong" }); }); Test Routes Use Postman or Thunder Client.

Introduction In my previous post, we went through the not-so-glamorous part: building LLVM from source and running a pass with opt. With that groundwork out of the way, it’s time to move on to the fun part which is writing the passes. In this post, we’ll start with a bit of theory on LLVM passes, just enough to give you solid footing, and then jump straight into code. Our first real pass will be a simple one: counting the number of add instructions across an IR module. Since we’ll be working directly with LLVM IR, I’m assuming you’re at least somewhat familiar with reading it. If not, I recommend taking a little time to get comfortable reading IR first because it will make your LLVM adventure much smoother. If I had to pick two pillars of LLVM, they would be the Intermediate Representati…  ( 12 min )

How many times have I forgotten to update my localization JSON file when I added a new key? I wanted to search for something that can give me more safety when I add a new key to the localization files. My first idea was to write a node script to check all JSON files in the locales dir, but then I found this useful plugin: 18n-Check Yes, I know: It doesn't have a lot of stars on GitHub, but I tried it and it works perfectly. Why do we have to recreate the wheel? Let's dive into this plugin. You can see all the documentation inside the Readme file on the GitHub repo. here to install the plugin I used the pnpm command pnpm add --save-dev @lingual/i18n-check Then we have to create a command in package.json like this: "i18n:check": "npx i18n-check --locales public/locales -s en -f i18next && i18n-check --locales public/locales -s it -f i18next" here I'm calling i18n-check with --locales option. With this you define which folder or multiple folders you want to run the i18n checks against. My structure files are this: . └── public/ └── locales/ ├── it/ │ ├── pricing.json │ └── external.json └── en/ ├── pricing.json └── external.json I used the && operator because i18n-check wants a target to compare the files from to start. In my case, I want to have every file notify me about missing keys or invalid translations. So if you use husky precommit you can configure that with this command: pnpm run i18n:check if you try to remove any keys from any files and launch the command you can see this: So with this, every change (add or remove) in the JSON localization file will be notified, and we have to update it. Thanks for the reading. See ya ✨  ( 7 min )

Context and Goal This task involved creating a simple API endpoint (/me) in any language and framework of choice so opted to using the Gin framework in Go. The critical requirement was that the API's response payload needed to include fresh data fetched from an external, third-party service Cat Fact Why have I chosen Go? I'm currently learning Go and this serves as an opportunity to make it a project based learning. The important architectural choice I faced was how to protect the third-party API from me. If my service goes viral(laughs) and gets 1,000 requests per second, I cannot afford to forward 1,000 requests to catfact.ninja. This would certainly cause me to be blocked. Hence, I resorted to limiting outgoing traffic by implementing a Token Bucket using golang's rate package to strictly control the flow leaving my service (strict 0.5 requests per second). If a request attempts to call the external API but the bucket is empty, we return a 429 Too Many Requests to the client, protecting the external service from my own overload. It seems I've successfully built an API endpoint that is not only functional but is also resilient (with Timeouts), reliable (with UTC timestamps), and architecturally sound (with proper traffic control). Also, I hope I have not bitten more than I can chew by joining the rigorous HNG Internship while learning a new language.  ( 6 min )

Urban life is noisy, fast, and often tiring—but it doesn’t have to be hostile. If you care about building better neighborhoods (as a resident, developer, or city official), you already know that walkability is a powerful lever for healthier, safer, more prosperous communities. In this guide, I’ll share a practical playbook for turning that principle into action—on the street, in code, and at city hall. In practice, that means learning to read the city through data, design, and daily routines, and yes, using tools like Walk Score profiles as a starting compass rather than the final word. Cities that invite people to walk do more than reduce traffic: they increase casual encounters, stimulate local businesses, and boost public health. When sidewalks feel safe and interesting, people choose t…  ( 10 min )

Data often hides intricate webs of relationships between multiple factors. In a world increasingly driven by analytics and machine learning, understanding how these factors interact is essential. Path analysis provides a powerful way to explore these connections. Imagine you want to predict the mileage of a car based on its attributes—such as horsepower, engine capacity, and number of cylinders. A simple linear regression might analyze the effect of one variable (say horsepower) on mileage. However, real life isn’t that simple. These variables interact; for instance, horsepower itself may depend on engine capacity or cylinder count. This is where path analysis becomes invaluable. It extends multiple regression by allowing complex interdependent relationships between variables. The Origins …  ( 9 min )

Intro When you need to monitor your resources with a CloudWatch alarm, what you normally have to do is to create an alarm with a specific matric of that resource. Although this gives a granular level of monitoring into your resources, you always have to add or remove alarms as and when you have new resources or when you remove a specific resource. Which is an operational overhead although it can be automated if you are using infrastructure as code tool. Another option available is to use aggregated metrics in your alarms such as CPUUtilization for EC2 so you have coverage, but at high level into a group of resources you need to monitor. The downside of this is that it lacks granular visibility into your individual resources. Also, there is only a limited number of resources that support …  ( 9 min )

Il giornalismo come scienza parte da una premessa semplice: i fatti sono ipotesi da verificare con metodi pubblici. Un titolo non è una verità, è un punto di partenza. La raccolta delle prove — documenti, dati, testimonianze, osservazioni sul campo — segue protocolli di tracciabilità: chi ha detto cosa, quando, con quali interessi e quali limiti. La verificabilità è il suo criterio di demarcazione. Come in laboratorio, si cercano fonti indipendenti e ripetibilità dell’informazione: la stessa affermazione deve poter essere controllata da altri. Le versioni alternative sono considerate “ipotesi concorrenti” e vengono testate finché non restano soltanto le spiegazioni più robuste. La metodologia giornalistica integra strumenti quantitativi e qualitativi. Dalle banche dati ai registri pubblici, dall’analisi di rete al fact-checking manuale, fino alle interviste in profondità: triangolare metodi riduce l’errore e illumina le zone d’ombra. Anche il dubbio è un dato: si dichiara, non si nasconde. L’etica funziona come normativa interna della ricerca. Trasparenza sugli eventuali conflitti di interesse, tutela delle fonti, proporzionalità tra interesse pubblico e danno potenziale: queste non sono “buone maniere”, ma condizioni epistemiche per produrre conoscenza affidabile. Senza etica, il risultato è contaminato. Infine, la divulgazione. Un buon articolo rende replicabile l’indagine: cita documenti, spiega il metodo, mostra i limiti. La forma non è solo estetica ma parte del contenuto: chiarezza, contesto e precisione permettono alla comunità di validare, confutare o estendere il lavoro. Così il giornalismo diventa un sapere cumulativo.  ( 6 min )

Week 10 – Auto Scaling, Serverless, and Databases Week 10 Like seriously—Week 10 already! 💃 I’m counting down because this journey hasn’t been easy, but I’m so grateful for my coursemates and the facilitator (Akeem Oyebanji). They make learning smoother and fun. Before you know it, it’ll be break time and then closing for the day. So cool! Today at Restart, we dove into Auto Scaling—trying to understand how it works and how to troubleshoot it. We got a surprise visit from the CTO of CIL Academy, Blessing U. Even though he could only stay for about 30 minutes, it was wonderful having him with us. Lately, we’ve been doing a lot of debugging. It’s not just about theory anymore. Debugging helps us truly understand the concepts. Each issue we fix adds another layer of learning. Today at Restart, we started learning about serverless architecture. We explored how to use AWS Lambda to subscribe to an SNS topic. It was exciting to see how serverless makes automation easier. For today, our focus was on AWS Step Functions and how they simplify workflows by connecting multiple services together. It’s amazing how AWS tools make complex processes so seamless. Today at Restart, we talked about databases. In my Week 7 article, I wrote about this topic, but this time we went deeper—learning about services like Amazon Aurora and Redshift. We also discussed database migration using AWS DMS (Database Migration Service) and how to choose the right service for different needs. This week felt like the bridge between what we’ve learned and how it all connects. From auto scaling to serverless and databases, everything is starting to click. Debugging has become part of my daily routine, and honestly, that’s how understanding truly grows.

WTF is this: Full-Stack Development with Rust Ah, the elusive dream of building anything you want, without needing a team of experts in different programming languages. Sounds like a myth, right? Well, welcome to the world of Full-Stack Development with Rust, where this dream might just become a reality. But, what does it all mean? Let's break it down. "Full-stack" refers to the ability to develop both the front-end (what users see and interact with) and the back-end (the behind-the-scenes logic and database) of a web application. Traditionally, this requires knowledge of multiple programming languages, like JavaScript for the front-end and Python or Ruby for the back-end. But, with Rust, you can potentially do it all with one language. Rust is a programming language that's known for its…  ( 10 min )

The recent release of Python 3.14 was one of the most hotly anticipated of recent years. Why? Well, there are several enhancements to the language, but the most significant of these is the release of an official version without the Global Interpreter Lock (GIL).

In this post, we’ll explore how to combine Angular’s Signals with Dependency Injection to create predictable, reactive, and reusable component state. A Signal is a reactive value that notifies dependents when it changes. Example: import { signal } from '@angular/core'; const count = signal(0); count(); // 0 count.set(1); Managing State via Dependency Injection Create a StateService that holds signals. Provide it at the component or root level. @Injectable({ providedIn: 'root' }) export class CounterState { count = signal(0); increment() { this.count.update(c => c + 1); } } Scoped State with Component Providers @Component({ selector: 'app-parrent', providers: [CounterState], templateUrl: './parent.html' }) export class ParentComponent { state = inject(CounterState); } Using the State in child Components @Component({ selector: 'app-child', template: ` + Count: {{ state.count() }} ` }) export class ChildComponent { state = inject(CounterState); } Best Practices Keep services pure and focused on state logic. Avoid too much global state. Use computed for derived state. Prefer DI scoping over manual signal creation in many components. A complete example is here Conclusion The main benefits: Reactive updates with zero boilerplate Clean state isolation using DI Easier debugging and reasoning Next steps: Try integrating Signals in existing projects Explore computed() and effect() for advanced patterns Happy coding! I hope you found it helpful. Thanks for reading! Medium: https://medium.com/@nhannguyenuri/ Dev: https://dev.to/nhannguyenuri/ Linkedin: https://www.linkedin.com/in/nhannguyenuri/  ( 8 min )

DeepSeek-OCR represents a major advance in AI technology, offering 10x token compression for document processing. This innovation could transform how AI handles memory and context, potentially reducing the need for traditional methods like RAG. Let's break down what this means and why it matters for AI systems. DeepSeek-OCR converts documents into compressed visual representations. It achieves this by transforming text into 2D grids, using a compression module that shrinks data without losing key details. For example, a 1024x1024 image might use only 256 tokens instead of thousands. This approach keeps about 97% accuracy at 10x compression. In practice, it processes documents more efficiently than rivals, handling high volumes on a single GPU. Key specs include support for various resoluti…  ( 7 min )

Cryptography: The Hidden Engine Powering Web3 The internet is changing fast. Web3 is the newest version of the web that promises more control for users and less power for big companies. But how does it work? The answer lies in cryptography, a type of secret code that keeps everything safe and trustworthy. Cryptography is all about turning information into secret messages. It helps protect data, make sure it’s not changed, and prove that things really come from who they say they do. In Web2, companies control your data and trust is based on them. Web3 changes that by using math and secret codes so you don’t have to rely on anyone else. This means you can own your digital identity, money, and information securely. Here are some simple ways cryptography powers Web3: Keys That Unlock Your Ac…  ( 7 min )

JavaScript looks simple — until it isn’t. Here are 10 JavaScript concepts that often fool even experienced developers 👇 == does type coercion, while === doesn’t. 💡 Lesson: always use === unless you enjoy debugging existential crises. this depends on how a function is called, not where it’s written. 💡 Lesson: use arrow functions or .bind() when passing methods around. Closures happen anytime a function “remembers” variables from its parent scope. 💡 Closures power things like React hooks, private variables, and debounce functions. var is function-scoped, not block-scoped — and gets hoisted to the top. 💡 Use let and const — they save you from strange timeline bugs. Functions get hoisted too — but only declarations, not expressions. It’s just a queue system. setTimeout(fn, 0) doesn’t run immediately — it goes to the queue. 💡 JS runs synchronously first, async tasks wait their turn. Even if they look identical: 💡 Two separate objects never share the same reference. Yes. It’s a 25-year-old bug that’s now part of the spec. 💡 Don’t trust typeof blindly. Use strict checks when needed. 💡 Always give fallback values if you’re not sure about array/object shapes. 💡 It’s the only value in JS that’s not equal to itself. JavaScript keeps you humble — just when you think you’ve mastered it, it throws something weird your way. Keep experimenting, stay curious, and you’ll never stop leveling up as a developer.  ( 7 min )

Did you know you can send multiple HTTP requests in parallel in Laravel, instead of one after another? That’s what Http::pool() does. It’s built on top of Guzzle and can massively boost performance when fetching data from several APIs at once. 🧠 The idea Normally, you might do this: $response1 = Http::get('https://api.example.com/users'); $response2 = Http::get('https://api.example.com/posts'); $response3 = Http::get('https://api.example.com/comments'); Each waits for the previous one. With Http::pool(), Laravel runs them all at once — so the total time ≈ the longest single request (around 1 second here). 🧩 Example use Illuminate\Support\Facades\Http; $responses = Http::pool(fn ($pool) => [ $pool->as('users')->get('https://api.example.com/users'), $pool->as('posts')->get('https://api.example.com/posts'), $pool->as('comments')->get('https://api.example.com/comments'), ]); $users = $responses['users']; $posts = $responses['posts']; $comments = $responses['comments']; $usersData = $users->json(); ⚙️ How it works The pool() method accepts a closure. Inside, you define multiple requests. Laravel runs them concurrently using Guzzle promises. Returns an array of responses (each is a standard Response instance). 🧩 Dynamic example $urls = [ 'https://api.example.com/products/1', 'https://api.example.com/products/2', 'https://api.example.com/products/3', ]; $responses = Http::pool(fn ($pool) => collect($urls)->map(fn($url) => $pool->get($url))->all() ); foreach ($responses as $response) { dump($response->json()); } 🛠 When to use it ✅ Fetch data from multiple APIs simultaneously 📚 Laravel Docs 💬 Have you used Http::pool()before?

"Understanding Scope in JavaScript —" In JavaScript, scope defines where a variable is accessible within your code. Think of it as the visibility zone for your variables. There are three main types of scope in JavaScript: global, function, and block. If a variable is declared outside of any function or block, it lives in the global scope and can be accessed anywhere in your code. const siteName = "DevBlog"; console.log(siteName); // ✅ accessible everywhere When a variable is declared with var inside a function, it has function scope, meaning it only exists within that function. function greet() { var message = "Hello"; console.log(message); // ✅ accessible here } console.log(message); // ❌ ReferenceError If a variable is declared using let or const inside curly braces { } — like in an if statement or a for loop — it has block scope and is only accessible inside that block. if (true) { let count = 5; const status = "active"; } console.log(count); // ❌ ReferenceError A common pitfall in JavaScript is the var trap. Variables declared with var are function-scoped and do not respect block boundaries, which can lead to unexpected behavior. for (var i = 0; i < 3; i++) { // do something } console.log(i); // ✅ 3 (leaked outside loop) Using let or const fixes this issue because they are block-scoped: for (let i = 0; i < 3; i++) { // do something } console.log(i); // ❌ ReferenceError To write clean and bug-free code, follow these best practices: Prefer let and const over var. Use const when a variable shouldn’t change. Keep variable scope as narrow as possible. Avoid polluting the global scope. Understanding how scope works helps prevent naming conflicts and keeps your code predictable. It’s one of those core concepts that, once mastered, makes debugging and refactoring much smoother. 🧠 Master scope → Debug less → Code smarter.  ( 7 min )

Introduction In today’s fast-paced world of web development, many developers focus on speed — shipping features as quickly as possible. But speed without structure often leads to technical debt and fragile systems. I’m Sain Bux, Full Stack Developer at TechMatter, and my approach to software engineering has been heavily influenced by research. By applying research-based methods — what I call evidence-based engineering — I’ve learned to make development decisions that are not just fast, but data-driven, scalable, and sustainable. In academic research, every conclusion must be backed by evidence — experiments, data, and peer review. Measured performance, not intuition. Documented results, not assumptions. Iterative testing, not one-time experiments. Instead of “I think this will work,” evi…  ( 7 min )

What these terms actually mean Common Language Runtime (CLR) Managed Code Unmanaged Code Interoperability (Interop) The Common Language Runtime (CLR) is basically the core engine of the .NET environment. It takes care of memory management, threading, code security checks, compilation, and execution — plus a bunch of system-level services like automatic memory management, security boundaries, type safety, and just-in-time (JIT) compilation. All these features are built right into the managed code that runs on top of the CLR. In other words, your C# program doesn't run directly on the operating system — it runs on the CLR. Managed code is code that runs under the supervision of the CLR. It can be written in any .NET supported language — C#, F#, VB, and so on. When you compile your source cod…  ( 7 min )

Writing code is one thing—but writing clean, readable, and maintainable code is another. Clean code not only makes your programs easier to understand but also saves time and reduces bugs in the long run. Whether you’re a beginner or an experienced developer, following clean code practices is essential. Meaningful Naming Variable, function, and class names should clearly describe their purpose. Avoid vague names like x or temp unless in a very short scope. For example: a = 10 max_user_attempts = 10 Clear names make your code self-documenting, reducing the need for extra comments. Keep Functions Small and Focused A function should do one thing, and do it well. Large functions are hard to read, test, and maintain. For instance: def process_data(data): def clean_data(data): def analyze_data(…  ( 7 min )

Over the past few months I have invested some time to contribute to an open source project I find fascinating: wasmCloud. As a platform engineer and architect, I am very familiar with how software platforms are typically built in practice. However, with the ubiquity of Kubernetes, you run the risk to being stuck in the "doing it the Kubernetes way" line of thinking. But then again, are there any better ways? This is where wasmCloud caught my attention. A modern platform building on proven concepts from Kubernetes, but with some significant differences. In this article I want to introduce wasmCloud, how it compares to Kubernetes, what its internal architecture looks like, and what ideas are, in my humble opinion, a step up from "the Kubernetes way of things".

The Spark: My First DevFest @ IUEA Then, @DeniseAllela took the stage. Her voice cut through the noise with a clear, powerful message: "AI isn't replacing developers—it's empowering them." It wasn't about being obsolete; it was about getting superpowers. The next hour was a blur of revelations. I watched the demo of Firebase Studio powered by Gemini 2.5, realizing full-stack AI development wasn't a future promise—it was here now. The concept of Jules, a fully autonomous coding agent, hit me like a jolt. Wait, I could spend less time debugging and more time designing? But the real game-changer was seeing the Gemini CLI in action. Watching someone automate complex operational tasks with a few simple prompts, instantly grounded by Google Search for real-time information, felt like watching magic. The tools weren't just fast; they were smart. Walking out into the Kampala afternoon, the world felt different. I wasn't just a developer anymore. I was an architect of agentic systems. My mind was buzzing with project ideas, already imagining how to integrate AI agents into the app I'd been stuck on. The takeaway wasn't just a hashtag; it was a mandate: #BuildSmarterShipFaster. DevFest didn't just give me new tools; it fundamentally changed how I saw my own potential. The future of code had arrived in Kampala, and I was ready to build it.  ( 6 min )

In the bustling office environment where I worked, stories about Xiao Yu had circulated long before I actually met her. Colleagues described her as a "disobedient" child—outwardly timid but inwardly rebellious, employing a strategy of non-cooperation whenever her parents imposed their will. Despite being enrolled in multiple tutoring programs, her academic performance hadn't improved; instead, her resistance had intensified to the point of developing an aversion to school. Ms. Li from our office would frequently share her frustrations, leaving the rest of us to offer little more than sympathetic sighs. One afternoon, returning from an errand, I noticed a girl in a white shirt sitting quietly in our office, completely absorbed in a book. When our eyes met, she offered a slight smile and nod…  ( 8 min )

Vim. It was a name that inspired both awe and fear. No, I am not talking about this: I meant this: For a very, very long time, I was reluctant to use Vim. I thought it was for experts and those ultra-legend programmers of yore. If quitting Vim was supposedly enough of a meme, then actually doing anything in it would be the stuff of legends, right? Well, last year, my friend started using it. And making some cool stuff. Things like nvim, nerd-tree, tmux, neofetch, etc, made it seem like he had ascended to the next level of programmer-kind. And then he showed it to me and said: “Learn and use Vim; it is very useful and easy. It is up to you, of course, but if you don’t, then I’ll silently judge you”. Very nice friend, I agree. But his challenge to me was the catalyst that led me to adopt…  ( 12 min )

Introduction Two minds. One goal — learning out loud. Hey everyone! Today, we’re starting with: Intersection of Two Linked Lists — a classic problem to sharpen your understanding of linked lists and pointers. We are given two singly linked lists, headA and headB. They might merge at some point, meaning from that node onward they share the same memory reference. Your task: return the node where the intersection starts. If the lists never meet, return null. Example: Intersection: node c1. Remember: Intersection is by reference, not by value. Idea: Why it works: a == b for any nodes a from list A and b from list B, we found the merge point. public ListNode getIntersectionNode(ListNode headA, ListNode headB) { for (ListNode a = headA; a != null; a = a.next) { for (ListNode b = …  ( 8 min )

Alle paar Monate liest man dieselbe Schlagzeile: „Mass Adoption steht vor der Tür.“ Doch sobald man eine typische Web3-App wirklich benutzt, wird schnell klar, warum wir noch weit davon entfernt sind. Die UX im Kryptobereich ist nach wie vor zersplittert, und genau hier können wir Entwickler ansetzen. Schon einfachste Aktionen bestehen aktuell aus zu vielen einzelnen Schritten: mehrere Wallets mehrere Chains unerwartete Gas Fees Bridges, Swaps, Signatur-Pop-ups, Approvals externe On-Ramps und Off-Ramps Für neue User ist das keine „dezentrale Freiheit“. Es ist ein Hindernisparcours aus Reibungspunkten. Was die Nutzer wirklich wollen (Spoiler: Nicht mehr Features) Sie wollen: ✅ Onboarding in einem Flow Wenn eine normale Banking-App so funktionieren würde wie ein durchschnittliches dApp-Interface, würde sie niemand benutzen. Es gibt aber positive Entwicklungen Fairerweise: Das Ökosystem macht Fortschritte. Account Abstraction setzt sich durch mehr menschenlesbare Transaktionen integrierte Fiat-On-Ramps (Dienste wie MoonPay lösen zumindest ein großes Hindernis) Wallets, die endlich UX statt nur „Power Features“ priorisieren Zum ersten Mal sehen wir Web3-Produkte, die sich wie echte Produkte anfühlen — nicht wie Prototypen. Wie Entwickler echte Adoption voranbringen können Wir sollten uns fokussieren auf: Komplexität abstrahieren (Kette verbergen, Aktion in den Vordergrund) Fehlbedienungen abfedern (Warnungen, Simulationen, Guardrails) Für Nicht-Techniker zuerst designen Die ersten 5 Minuten perfektionieren (Onboarding entscheidet alles) Die nächste Nutzerwelle wird nicht von der besten Technologie gewonnen, sondern von der reibungslosesten Nutzererfahrung.  ( 6 min )

Binding in XAML is one of the cleanest ways to keep your UI and logic in sync. You just have to know how it thinks. Once you understand how {Binding} and {x:Bind} behave under the hood, how they resolve data, when they update, and what they quietly ignore, it stops feeling like magic and starts feeling like control. These are the ten common binding pitfalls that, once you spot them, make XAML feel like the powerful, predictable system it was meant to be. Your binding path looks correct but nothing displays. The Visual Studio XAML Binding Failures window shows "Cannot resolve symbol" errors. You forgot to set DataContext on the element or any of its ancestors. Fix it by setting DataContext explicitly in code-behind or XAML, or use ElementName or Source to bypass DataContext entirely. In Win…  ( 9 min )

In modern engineering organizations, DevOps is no longer about “running deployments” — it’s about empowering developers to build, deploy, and scale safely and independently. Over the last few months, I’ve been refining a Platform Engineering playbook focused on one simple goal: 👉 Enable developers to self-serve infrastructure — securely, efficiently, and with full cost visibility. Here’s what I’ve learned along the way: 💡 Golden paths beat golden rules — instead of more docs, create reusable templates that guide developers down the right path. 🧱 Guardrails, not gates — automate compliance and security checks via policy-as-code (OPA, Kyverno, Sentinel). 💰 FinOps from day one — right-sizing defaults, TTLs for ephemeral environments, and showback dashboards prevent surprise invoices later. ⚙️ Platform = Product — maintain a roadmap, collect feedback, track adoption, and measure value (DORA, SLOs, cost savings). When done right, this shift reduces lead time by 60%, infra tickets by 70%, and cloud spend by up to 25%.

Creating terraform or other infrastructure as code for a new project can be daunting for some. This shows how you can easily crank out a new deployment to meet your requirements using Github copilot prompt files and a few free MCP servers. For the heck of it, we will also convert between two totally different cloud providers to deploy the same infrastructure. Github copilot is getting more powerful with each update and I've been enjoying using it quite a bit to write quick scripts and even initializing whole project repositories for me. But I've never been very impressed with it (or any other LLM's) ability to create solid terraform. I've been exploring model context protocol (MCP) servers quite a bit lately and figured perhaps they can augment an agent with enough additional capabilities …  ( 13 min )

Modern websites need to look great on all devices, and developers need layout tools that can handle complexity without chaos. While Flexbox is fantastic for one-dimensional layouts, it starts to feel limited when you need to structure both rows and columns at once. That’s where CSS Grid Layout comes in—a powerful, grid-based system for crafting two-dimensional layouts. CSS Grid Layout is a modern CSS module that gives you control over both rows and columns at the same time. Think of it as creating a blueprint—a grid made up of intersecting lines—where you can neatly place items wherever you want. Instead of battling floats or relying on nested flexboxes, Grid allows you to describe your layout in a declarative way: The browser does the heavy lifting. The code is cleaner and easier to maint…  ( 8 min )

What Really Happened in the AWS US-East-1 Outage and Why It Was So Bad: An Initial Writeup Based on AWS Communications While many tech professionals have detailed AWS’s recent US-East-1 outage, my view is shaped by extensive experience managing DNS outages in on-premises environments. This writeup is an initial analysis based on AWS’s official statements and public information. DNS outages are a fundamental failure point in any distributed system. No provider, including AWS, can fully eliminate DNS risk. Yet in on-prem environments, DNS disruptions—even with tight application dependencies—usually recover fast and stay localized, enabling quick service restoration. AWS operates at hyperscale—millions of interdependent APIs, services, and control planes deeply coupled and globally dispers…  ( 9 min )

When we build APIs or services that accept frequent requests — like a website analytics tracker, login endpoint, or public data API — we eventually face one of the oldest scaling problems on the web: what if someone calls it too often? That’s where rate limiting comes in. Rate limiting is the practice of controlling how many times a user (or client) can perform a certain action within a defined time window. It protects your system from: Accidental overloads (like retry storms) Misbehaving scripts or bots Denial-of-service attempts Excessive costs (for APIs that bill per request) In short: you decide what “too much” means, and then enforce it gently but firmly. Every rate-limiting strategy is built around three questions: Who are we limiting? (A user account, API key, IP address, browser…  ( 8 min )

Hi, today I want to talk about how I expanded my CLI tool’s functionality by analyzing another similar open-source project, Repomix. Before diving into the code, I wanted to get a sense of what the project actually did, so I started with the web version. The visual interface helped me understand its features a lot faster than just staring at files full of unfamiliar code. After experimenting with the web version, I noticed several useful options: you could compress code, remove comments, and strip empty lines. These features seemed really practical since I often use my own repository packaging tool for personal projects, and even after packaging, there’s usually a lot of irrelevant content left. I really liked how Repomix handled this problem, so I decided to see how it implemented these f…  ( 7 min )

State Updates Managing arrays in React state is a fundamental skill, especially when dealing with dynamic data like a list of users, products, or, in this case, selected items. While array methods like map are great for updating every item, what happens when you only need to change one specific entry based on an ID or name? That's where the JavaScript method findIndex() shines, particularly when paired with the immutability principles of React state updates. This post will walk you through using findIndex() to locate an item's index and then safely update that item in a TypeScript React application. findIndex() Over find()? When you need to modify an item in a React state array, you can't just change the item directly. React demands immutability: you must create a new array with the up…  ( 9 min )

🧠 Discussion post Many major breaches weren’t flashy zero-days — they were long-dwell intrusions where an attacker lived quietly inside the network for months or even years. For anyone managing infrastructure or doing security work: What’s the biggest blind spot that lets attackers stay undetected for so long? Here are a few ideas I’ve heard from practitioners: 🔍 Limited visibility or incomplete telemetry 👥 Weak identity / credential hygiene 🌐 Flat or poorly segmented networks 📜 Incomplete or tamperable logging 🧠 Or maybe something completely different? I’m exploring how containment and audit automation could shorten dwell time — still in the probing phase and looking to learn from real experiences. If you’ve seen long-dwell attacks first-hand, or built monitoring/segmentation that actually worked, I’d love to hear what made the difference. 👉 Drop a comment with your observations or favorite tools — I’ll summarize the best insights in a follow-up post.

Last week, I started a new series documenting the journey of building Disco, a more effective networking app for in-person events. We also formed our first pilot partnership with York University, which helped validate the idea early on and gave us real-world feedback to shape our next steps. For the past two weeks, I've been building Disco with two friends. A small, scrappy team that believes in the idea as much as I do. As I started sharing about Disco more, demoing it at friends' parties, at the Startup Open House event that recently took place in Toronto, and even to incubators such as the DMZ, new ideas kept coming in and the feedback was amazing. Every conversation helped me refine what matters most for our MVP and where we should focus next. I used to be terrified of talking about my…  ( 7 min )

Researchers at Mila have proposed a new technique that makes large language models (LLMs) vastly more efficient when performing complex reasoning. Called Markovian Thinking, the approach allows LLMs to engage in lengthy reasoning without incurring the prohibitive computational costs that currently limit such tasks. The team’s implementation, an environment named Delethink, structures the reasoning chain into fixed-size chunks, breaking the scaling problem that plagues very long LLM responses. Initial estimates show that for a 1.5B parameter model, this method can cut the costs of training by more than two-thirds compared to standard approaches. The quadratic curse of long-chain reasoning For an LLM to solve a complex problem, it often needs to generate a long series of intermediate “thinki…

OpenAI is entering the browser world with the launch of ChatGPT Atlas, an AI-enabled browser.  Atlas, now available globally, can be accessed through Apple’s macOS, with support for Windows, iOS, and Android coming soon. The announcement comes several months after rumors in July that OpenAI would release a web browser that would challenge the dominance of Google’s Chrome.  OpenAI will make a formal announcement via livestream with CEO Sam Altman presenting Atlas. With more people using AI models and chat platforms for web searches, launching an AI-enabled browser has become another battleground for model providers. Of course, as Chrome has become more popular, it has slowly added AI capabilities thanks to the Gemini models. But companies like Perplexity, with its Comet browser, hoped to take on Chrome. Opera, long a Chrome competitor, also repositioned itself as an AI-powered browser by embedding AI features into its platform.

If you’ve ever cracked open a .github/workflows folder, you probably felt that mix of resignation and dread that only YAML can inspire. Indentation errors, random on: vs jobs: confusion, the joy of debugging a misaligned dash — truly a rite of passage. If you’re lucky, GitHub Actions is the only place in your stack where you still have to deal with YAML on a daily basis. For the rest of us, it’s an ever-present reminder that whitespace is a cruel and unforgiving god. Thankfully, we don’t have to hand-craft every workflow file anymore. You can generate them, reuse them, or even visually design them — the YAML just happens to be the final delivery format. GitHub itself has been improving the situation: first with reusable workflows and composite actions, and more recently by adding YAML anch…  ( 9 min )

Intro This small article is about algebraic data types and their surrogates in C#. GitHub The term algebraic data type is from the functional paradigm. Discriminated unions. What about C#? It still does not have its implementation, but the development finally started after several years of moving the proposal to the next year. If the term discriminated unions is new to you, it would be easy to read the article on Microsoft Learn F# documentation Discriminated Unions. Let's start with an example and F# - we need to create a bank account and process a payment for a bank account. type BankAccountCommonData = { Title: string; BankName: string; BankAddress: string } type BankAccount = | Iban of common: BankAccountCommonData * Number: string | Swift of common: BankAccountCommonData *…  ( 19 min )

Whenever we create an object for a class, a constructor will be executed and the name of a constructor is similar to the class name. Constructors are like methods even though they never have a return type & can’t return any value. They can have all the access levels, and they are also called non-static initializers, which are used to initialize an object & can’t be static. class class_name { className(){ } } className rv=new className(); Use our Online Code Editor package oops; public class A { A() { System.out.println("Running Constructor"); } public static void main(String[] args) { …  ( 8 min )

Approach Showdown: Modular vs. Holistic Autonomous Systems When it comes to designing autonomous systems, two prominent approaches dominate the landscape: Modular and Holistic. In a Modular Autonomous System, decentralized architectures are employed, comprising independent modules that communicate through standardized interfaces. This approach offers several advantages, including: Scalability: New modules can be easily integrated, enabling the system to adapt to changing requirements. Fault Tolerance: If one module fails, the others can continue to function, minimizing downtime. Flexibility: Modules can be developed and updated independently, allowing for rapid innovation. On the other hand, a Holistic Autonomous System takes a more integrated approach, where all components are tightly linked and work in concert to achieve a unified goal. This approach excels in: Simplification: Fewer interfaces and a more streamlined architecture can reduce c... This post was originally shared as an AI/ML insight.

The prospect of AI-powered cybersecurity systems combating insider threats is an intriguing one. However, their reliance on data may indeed create a paradox that makes them vulnerable to sophisticated social engineering attacks. Social engineering exploits human psychology, often targeting employees' trust and curiosity. Insider threats can be particularly damaging as they involve individuals with authorized access to sensitive information. AI-powered systems, while adept at pattern recognition and anomaly detection, may struggle to identify subtle manipulations by insiders. For instance, an insider might create a convincing phishing email that appears to come from a trusted colleague or executive, using language and tone that mimics the original sender. The AI-powered system, trained on vast amounts of data, might flag the email as legitimate, unaware of the insider's intentions. Moreover, AI systems may over-rely on data, potentially leading to "training data poisoning" - a sce... This post was originally shared as an AI/ML insight.

Get ready for liftoff! 🚀 Researchers have developed a groundbreaking AI fairness framework that defies conventional wisdom by intentionally injecting bias into AI models. This novel 'adversarial fairness' technique flips the script on traditional approaches, where the goal is to eliminate bias altogether. Instead, the aim is to make AI models more robust against data manipulation and adversarial attacks. By introducing a controlled amount of bias, these models can better detect and mitigate the effects of malicious data tampering. Think of it like a digital 'immune system' that can anticipate and counter potential threats. This approach could revolutionize AI's ability to detect anomalies, identify biases, and make more accurate predictions. Imagine an AI-powered fraud detection system that can differentiate between genuine and manipulated data. Or a medical AI model that can spot biased data and provide more accurate diagnoses. The potential applications are vast, and the implica... This post was originally shared as an AI/ML insight.

You've probably all heard at least in passing about Loader's number, a truly massive googological monster. But if not, here's a brief explanation: Loader's number is one of the largest numbers ever to appear in a serious mathematical context, and it's famous specifically within the googology community. It was obtained in 2002 by programmer Ralph Loader as a result of his program, which won a competition for writing the most efficient program for output in Lambda Calculus. The foundation is lambda calculus. This isn't just an algorithm written in C++ or Python. It operates in a fundamental system that underlies functional programming and computability theory itself, giving the number immense "mathematical density." And as the cherry on top – it surpasses other giants: Loader's number is inc…  ( 11 min )

The shiny new testing suite wasn't bought because it was the best. It was bought because the vendor knew the manager's spouse.

Organizations pour millions into "the ultimate" testing tool, convinced it will cure their quality woes. The tools are powerful — but power without purpose is chaos. ⚡ And here's the paradox: the more expensive the tool, the more people assume it must deliver value.

In any design or engineering environment, sharing technical drawings efficiently can make or break a project’s timeline. CAD files like DXF are excellent for creating and editing detailed designs, but they’re not always practical for communication. Clients, contractors, or partners may not have CAD software, which can lead to confusion, file incompatibility, and wasted time. That’s why learning to convert DXF to PDF is such an important part of modern design workflows. Converting your files to PDF ensures that your drawings can be opened and viewed by anyone, on any device, without special tools. PDFs preserve the quality and accuracy of your original designs—including layers, dimensions, and line weights—while being lightweight and easy to share. The benefits extend beyond accessibility. …  ( 7 min )

I think of a delegate as a reference to a function. It’s a type that says “I can point at any method that has this parameter list and this return type.” You create one, point it to a compatible method, and call the method through the delegate. Because you can pass delegates around, they’re great for plugging behaviour into APIs. C# events are built on delegates too. Think of a delegate like a phone number you hand to someone with simple instructions: “when It's done, call this number and say something” // 1) Declare a delegate type public delegate string Greeter(string name); // 2) Point it at compatible methods static string Formal(string name) => $"Hello, {name}."; static string Friendly(string name) => $"Hey {name}!"; // 3) Invoke through the delegate instance Greeter g = Formal; //…  ( 8 min )

Hi everyone, I'm Ellie. I'm a Senior .NET Engineer now, but my career actually started in game development using Unity and C#. That transition from games to backend services gave me what I feel is a unique perspective on the specific challenges developers can face when moving into the .NET ecosystem. As a mentor, I've recently guided a few engineers through this exact transition. I found myself repeatedly sketching out the same core concepts and tools that seemed essential for day-to-day work in a large-scale company. To help others on the same path, I’ve tried to turn that advice into what I hope is a practical roadmap. While there are many excellent .NET roadmaps out there, this one is my attempt to capture the day-to-day realities of a .NET engineer. It covers concepts and libraries tha…  ( 7 min )

Caching is a well know abstraction in programming, we see it every where, from our CPU, to keep data in a memory storage faster than the RAM, to CDNs, for delivering content faster to the user. It's usually used as an optimization factor in systems that need a slower latency in read operations. Thus, understading what it is and how to implement it in applications is a good knowledge to have overall. In Web Development, the Cache is a layer that usually sits between our persistent data storage and the application. Its purpose is to make access to frequently used data cheaper/quicker by having these information in the cache available for read operations. In this article we'll cover read and write implementations for caching in our backend, but first I'll explain some important topics. Consis…  ( 19 min )

From zero data engineering experience to deploying a streaming analytics platform powered by Azure's student tier I created an end-to-end IoT data pipeline that ingests simulated sensor data, detects anomalies in real-time, stores everything in a database, and visualizes live metrics on a Power BI dashboard.

When a browser loads a website, it downloads HTML, CSS, JavaScript and other text based files. These files can be large which makes websites load slowly on slow networks. To solve this problem servers compress files before sending them to the browser. The browser then decompresses them and shows the page normally. Two popular compression formats used on the web today are Gzip and Brotli. Gzip is one of the oldest and most trusted compression formats for websites. It was introduced in the 1990s and is still supported by almost every browser and server. When a browser sends a request it sends a list of compression formats it supports using the Accept-Encoding header. If Gzip is one of them the server compresses the response using Gzip and the browser handles the rest. Gzip is simple and reli…  ( 7 min )

Introduction In my last article, I discussed the data files that power my sensor fusion project. But raw data alone isn't enough. The real challenge begins when you must transform those satellite ephemerides and reference trajectories into physically meaningful measurements that a rover can use to navigate. Today I want to share how I built the core of my system: the GNSS Measurement Engine. This is the component that takes static data and converts it into a dynamic simulation of how satellite signals interact with my rover. The engine's main goal is simple in concept but complex in execution: generate corrected GNSS measurements that are realistic enough to feed into my future end to end system. In practical terms, this means taking known satellite positions (SP3), antenna corrections (…  ( 9 min )

October 20, 2025 — In the early hours of Monday morning, millions of internet users worldwide woke up to find their favorite apps and services completely unavailable. Snapchat wouldn't load. Wordle was inaccessible. Medium not loading. Vercel was not working. Ring doorbells went dark. Amazon's own shopping site displayed error pages featuring apologetic dog photos. The culprit? A massive outage at Amazon Web Services (AWS), the cloud computing giant that quietly powers much of the modern internet. The outage began at 12:11 a.m. PT (3:11 a.m. ET) when AWS reported an "operational issue" affecting 14 different services in its U.S.-East-1 Region center in northern Virginia. What started as a technical glitch in a single data center quickly cascaded into one of the largest internet disruptions…  ( 10 min )

Thinking about using public AI tools like ChatGPT for sensitive legal work? You should know the risks before diving in. These AI tools aren’t built with strict legal confidentiality in mind, so whatever you share might get stored, used for training, or accessed in ways that could put your client information at risk. That could mean accidentally exposing data and running into privacy laws like GDPR or HIPAA. Unlike private AI setups made for law firms, public platforms don’t give you much control over your data. Sure, you might get some clever answers, but your sensitive info could end up places it really shouldn’t in legal work.

Most teams ship features; too few ship repeatable workflows. This article shows how to turn fragile, one-off media scripts into a resilient containerized pipeline you can run locally, on a VM, or in CI with minimal fuss. For illustration, I’ll reference an example container such as this Docker image to ground concepts—use any base image you trust; the method is what matters. By the end, you’ll have a blueprint for packaging your media processors, scheduling posts through official APIs, and scaling the whole setup without turning your laptop into a build farm. If your content workflow involves a sequence of “tiny tasks” (resize images, transcode short clips, add subtitles, extract captions, queue publish jobs), chances are it’s stitched together with brittle shell scripts and a README only …  ( 9 min )

When I'm writing this I'm still on the train back from ReactJSDay, the largest conference on ReactJS in Italy, reflecting on something that happened from the audience. I gave my talk about TanStack Start, showcasing why I like this full stack framework and how it is powered by TanStack Router, my favourite routing library as of today. At the end of the session I got a question about how much effort would it take to migrate a very large React Router codebase to TanStack Router. My answer has been honest: I’ve been lucky enough to always start fresh with TanStack Router or only migrate smaller project so I didn’t have a direct experience to share. By the book it is indeed doable (and there’s a migration guide in the docs), but that was it from my side. However, during lunch there was a board…  ( 7 min )

I started in enterprise development believing technology was the answer. Fifteen years later I know it’s rarely the first one. I’ve worked with hundreds of clients and built thousands of systems. The lessons are sharp. The stats are unforgiving. Everyone talks “scale” as if it’s the end-game. In reality most enterprise systems struggle with clarity, not traffic. In public sector studies large IT projects averaged a 24 % schedule overrun, but 18 % were outliers with cost overruns >25 %. One study found cost overruns follow a power-law: most projects modestly overrun but a small number explode. For enterprises the question should be “how simple can we keep this” rather than “how big can we make it.” Development frameworks proliferated. Agile, DevOps, SAFe became religious. Yet success did …  ( 8 min )

Supporting multiple live instances of an application that interact with a single relational database where the schema and data must remain consistent throughout deployments is significantly more complex than migrating with just one instance, or in a simple "stop all instances, migrate, deploy" scenario. Let's explore how to perform seamless rolling migrations with Flyway across multiple instances while ensuring high availability! Our original deployment strategy was straightforward: anchored by Flyway for database migrations and JPA with ddl-auto=validate, we would stop all instances, run migrations on the first instance at startup, and then start the remaining instances. This “stop the world” approach worked well under previous requirements—downtime during off-peak hours was acceptable, a…  ( 9 min )

Software is everywhere. Almost every part of our lives — from banking to maps to music — depends on it. And when software fails, it can cost money, waste time, or even cause real harm. As developers, that means we carry a great responsibility — the way we write code truly matters. Uncle Bob (Robert C. Martin), a renowned software engineer, instructor, and author, reminds us that clean code is more than just style — it’s about communication. Code is read far more often than it’s written, so clarity, consistency, and simplicity are essential. In this article, inspired by Uncle Bob’s Clean Code lessons on YouTube and Ryan McDermott’s JavaScript adaptation (clean-code-javascript), I created a quick and practical guide, blending my notes on these timeless principles to help improve your code.

Author: Ian Chen Linux Kernel has supported sched_ext since v6.12, which allows users to define custom CPU schedulers through eBPF programs. This feature enables developers to create more flexible and efficient scheduling strategies to meet specific performance requirements. The author was deeply inspired by the scx project and, referring to the concept of scx_rustland, implemented a framework scx_goland_core that allows developers to write custom schedulers using the Go language. Regarding the combination of 5G and scx, there has been some discussion [1] [2] [3]. However, considering the characteristics of modern Cloud-Native Apps (5G Core Network), there are currently no related cases exploring how scx operates on cloud-native architectures.

(This is an English translation of my original Japanese article: 日本語版はこちら) In slack-explorer-mcp, instead of returning permalink URLs for each message in the response, I have the AI Agent on the client side construct them. This is because including permalinks for every message would consume a significant amount of tokens. Since permalinks can be reconstructed from other data already provided, I omit them and let the client side build them to save tokens. However, this approach has been inconsistent—sometimes it works well, sometimes it doesn't. Currently, slack-explorer-mcp returns large responses in one-line JSON format. I wondered if changing to formatted JSON with line breaks and indentation (which is more human-readable) would also improve accuracy for LLMs. So this time, I evaluated h…  ( 8 min )

For years, I ignored SQLite. I assumed it was only good for toy apps, quick experiments, or maybe some desktop utilities. Like many developers, I immediately jumped to Postgres or MySQL for any "serious" project. I even paid for a managed AWS RDS instance, believing I was preparing for scale. But over time, I learned something that changed how I build small and medium-sized systems: 👉 For 90% of applications, SQLite is not only enough — it's often better. My entire application runs on a single VPS, serving just a few requests per second. Most startups never reach the mythical "millions of requests per minute". For this scale, running a full database server is like renting a truck to deliver a pizza. SQLite is a serverless, file-based, self-contained database engine. It's just a single fil…  ( 11 min )

In today’s interconnected world, APIs are the backbone of digital products. Whether you’re building a fintech platform, a social media app, or an internal microservice, the quality of your API design determines how easily others can build on top of your system. Poorly designed APIs cause frustration, confusion, and endless debugging sessions. But a well-designed API feels intuitive, like it’s reading your mind. A great API is like a conversation between humans. It should be predictable, consistent, and clear. Today, we’ll talk about the best practices in API design, and we’ll try together to put them into clear, understandable, and practical points that fit all developer levels. These practices will help you in your daily work, and it’s even recommended to treat them as a checklist when d…  ( 12 min )

Header image sourced from Chat-Deep Original post. In the fast-paced world of Artificial Intelligence, we often marvel at the size and capabilities of new Large Language Models (LLMs). However, behind every breakthrough lies an invisible wall—a fundamental challenge that limits their scalability and accessibility: computational cost. The team at DeepSeek AI seems to have made tearing down this wall their specialty. First, they introduced us to their DeepSeek-V2 model with its groundbreaking Mixture-of-Experts (MoE) architecture, a clever way to scale models by activating only a fraction of their parameters for each task. And now, they've done it again. With the release of DeepSeek-V3.2-Exp, they are tackling another pillar holding up that wall: the complexity of the attention mechanism. To…  ( 9 min )

Premise This guide is intended for Linux and macOS users. I haven’t tested this workflow on Windows, so its compatibility is not guaranteed. I work on a large Unreal Engine project and have been developing in Rider for a while. It worked fine, but last year I decided to learn Vim and installed its plugin in Rider. However, I soon ran into two issues: Rider was becoming increasingly heavy and sluggish for my Unreal Engine workflow. I work across multiple PCs, programming languages, and game engines, and I wanted a single setup that works everywhere. That’s when Neovim entered the stage. With this tutorial, I want to help you achieve a functional setup and workflow with Neovim and Unreal Engine, the simplest way possible.

In many web applications — support systems, lead management, code reviews, or on-call rotations — there’s a recurring need to assign work evenly across a group of people. I built round_robin_assignment to solve that problem in a clean, persistent, and concurrency-safe way for Ruby on Rails projects. This gem encapsulates a database-backed round-robin assignment algorithm that works across multiple app instances and survives restarts — no more reinventing the wheel for fair task rotation. I’ve seen many Rails apps try to “just rotate” assignments in memory, or store a pointer somewhere ad hoc — until concurrency, scaling, or team changes break it. round_robin_assignment is meant to be the opposite: ✅ Simple API ✅ Persistent in the database ✅ Handles multiple groups ✅ Adapts to changing …  ( 8 min )

Practical steps to make remote developers feel heard, trusted, and empowered. “Psychological safety is not a nice‑to‑have perk; it’s the foundation that lets high‑performing teams innovate faster.” – Harvard Business Review The pandemic accelerated a shift that was already underway: engineering teams are increasingly distributed across time zones, cultures, and career stages. While this brings unparalleled talent diversity, it also introduces friction points that can erode trust—especially when the only medium of interaction is Slack, video calls, or asynchronous comments on pull requests. In this article we’ll explore what psychological safety looks like for remote engineers, why it matters more than ever in a distributed context, and—most importantly—concrete actions you can take today t…  ( 10 min )

Idempotency in System Design: Full example Idempotency is a concept frequently mentioned in system design. I will explain what it means in simple terms, briefly address common misunderstandings, and finish with a full example. Something is idempotent if doing it once or multiple times gives the same outcome. In other words, if I do that something once, I get the same result as when I do it 2 times or 3 times or 10 times. Let's look at the standard example: we have an on and off button. Pressing them is an idempotent operation. If you press on once, the machine is on. If you then press it again, and again and again, nothing changes. The machine stays on. Same for the off button. Here's an example from programming: def hide_my_button(self): self.show_my_button = False This is clearly …  ( 11 min )

Most of us set financial goals — buying a car, saving for our child’s education, or even achieving financial freedom early. While building my expense-tracking and investment insight platform, I realized that most users weren’t just looking for expense analytics — they wanted guidance. They wanted a way to reach their goals confidently. So, I started building a new feature: A Goal-Based Investment Recommender The Idea The concept is simple but powerful. Users provide: 🎯 Target amount (e.g., ₹10,00,000) Based on these inputs, the system calculates: The required monthly SIP (Systematic Investment Plan) to achieve the goal. In short — users move from “I want to save ₹10L in 5 years” to “Invest ₹12,500/month in these 3 mutual funds”. Once the SIP is calculated, I match it with mutual fund schemes based on: Fund category (Equity, Hybrid, Debt) This recommendation engine helps users focus on execution, not confusion.  ( 6 min )

Understanding Skewness and Kurtosis in Data Distribution In statistics, Skewness and Kurtosis are two important measures that describe the shape of a probability distribution. These measures help in understanding how the data is spread out and whether it is symmetric or skewed. Skewness refers to the asymmetry of the distribution of a dataset. A perfectly symmetric distribution has a skewness of zero. If the distribution is skewed to the left (negative skew), the tail is longer on the left side. If it is skewed to the right (positive skew), the tail is longer on the right side. $$ Where: $ n $ is the sample size $ x_i $ is the $ i $-th data point $ \bar{x} $ is the sample mean $ s $ is the sample standard deviation Skewness = 0: Symmetric distribution Skewness > 0: Right-skewed (positive skew) Skewness 3: Heavy-tailed distribution (leptokurtic) Kurtosis < 3: Light-tailed distribution (platykurtic) Measure Description Formula Skewness Asymmetry of the distribution $ \frac{n}{(n-1)(n-2)} \sum \left( \frac{x_i - \bar{x}}{s} \right)^3 $ Kurtosis Tailedness of the distribution $ \frac{n(n+1)}{(n-1)(n-2)(n-3)} \sum \left( \frac{x_i - \bar{x}}{s} \right)^4 - \frac{3(n-1)}{(n-2)(n-3)} $ Understanding Skewness and Kurtosis is essential for analyzing data and making informed decisions in fields such as finance, economics, and social sciences.

During Stage 0 of the Backend Wizards program, I built a simple yet insightful REST API endpoint called /me using FastAPI. The goal was to return my personal profile information, fetch a random cat fact from an external API, include a dynamic UTC timestamp, and format everything neatly in JSON. While it looked straightforward, it pushed me to understand key backend concepts like API integration, error handling, and deployment. I structured the project using Python, FastAPI, and the requests library, managed environment variables with python-dotenv, and deployed it seamlessly on Railway. I learned to anticipate failures from external APIs by adding try-except blocks, format timestamps in ISO 8601, and configure environment variables properly for cloud deployment. Seeing my live endpoint— https://introproj-production.up.railway.app/me —work flawlessly was satisfying. More than just completing a task, this experience taught me how much discipline and attention to detail backend development truly demands, from clean code structure to reliable production deployment.  ( 6 min )

Hey devs 👋, If you’ve been diving into data engineering or working with big data systems, you’ve probably come across Apache Hive - and maybe thought: “Why does Hive feel so complicated?” Let’s break that down - how Hive actually works, why it’s built this way, and why that complexity is necessary for handling data at scale. What Hive actually is (and what it’s not) How it manages data & metadata Why its layered design makes sense How query execution works under the hood Why it’s still relevant - and where Trino, Spark, and others come in Not a Database - It’s a Data Warehouse Framework A lot of people confuse Hive with a database. But it’s not that. Hive is a data warehouse framework built on distributed storage like HDFS or S3. SQL - like interface (HiveQL) so analysts can query massi…  ( 8 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. 🧩 What I Built I built AI Roadmap Visualizer — a chat-based web app that transforms any roadmap text (like a README.md or project plan) into a visual learning path. It parses milestones, generates cards for each phase, and even creates pixel-style art for every milestone using the Imagen API in Google AI Studio. I wanted a tool that could visualize my own engineering roadmap — from Java monolith to cloud-ready platform — in a creative yet structured way. 🪄 Core prompt used in Google AI Studio: Create a web assistant that visualizes engineering roadmaps as a sequence of milestones with AI-generated art. Each milestone should have title, dates, focus, and deliverables. Keep the aesthetic neon-violet and pixel-tech inspired. 🎨 Demo Here’s how it works in action: 1️⃣ I paste my roadmap text roadmap-2025-2027/README.md. 💡 I also tested how the app adapts to different roadmap styles — from Frontend to Data Science and Creative AI paths: 🔗 Demo: AI Roadmap Visualizer — Google AI Studio Applet ✨ My Experience Building this project was a short but valuable dive into prompt-driven app design. Google AI Studio makes it surprisingly easy to go from idea → prompt → working prototype.  ( 6 min )

Ever left your water pump running and came back to a mini swimming pool on your terrace? I have. That's why I built this smart water pump controller using ESP32, Firebase, and a simple web dashboard. With just a browser, I can now switch the pump ON or OFF, detect leakage and even calculate the water usage bill. And yes, it’s as cool as it sounds. Whether you’re diving into IoT or just tired of forgetting to turn off your pump, this is a fun and useful project to try out. It’s also a great way to dip your toes into cloud-connected hardware without getting overwhelmed. In every other house, someone’s yelling "Hey, turn off the motor!" and someone else is replying "Oh no, I forgot!" 🤦🏼‍♂️ This everyday chaos inspired me to build a smarter solution, a system that lets me control the motor r…  ( 26 min )

In the previous part of this series, we built and flashed our first Zephyr app on the STM32 Nucleo-F401RE. Now, we’re going a step deeper embedding firmware version metadata right inside the image. The result is a self-describing binary that can tell you its build version at runtime — ideal for debugging, OTA rollbacks, and CI pipelines. The Zephyr shell subsystem lets you interact with your firmware over a UART, USB, or virtual terminal. Enable it in your project configuration (prj.conf): CONFIG_SHELL=y CONFIG_SHELL_BACKEND_SERIAL=y CONFIG_LOG_CMDS=y Re-build the app: west build -t run -d build_native_sim Typical console output on native_sim: -- west build: running target run uart connected to pseudotty: /dev/pts/4 *** Booting Zephyr OS build v4.2.0-6152-gfd51dde8f5ca *** [00:00:00.000,…  ( 9 min )

Stop modifying every pipeline. Learn how to collect CDEvents from platforms that already send webhooks - GitHub, GitLab, ArgoCD - by transforming their native events automatically. In Episode #3, you learned active integration - modifying pipelines to send CDEvents directly.

Introduction If you’re building a cloud app and you pick a region solely based on geography, you’re missing half the story. I recently used the tool CloudPing.info to validate latency from East Africa to AWS regions — and the results changed my architecture. I’ll show you how I did it and how you can too. Why I picked this tool CloudPing.info let me run latency tests from my browser to dozens of AWS regions instantly. No complex CLI-setup, no VPNs required. It gave me real numbers for my exact location. Once I had those numbers, I could shortlist regions based on actual latency, not just map distance. My step-by-step process Navigate to cloudping.info 1.Click “HTTP Ping” What I found From Nairobi: af-south-1 (Cape Town) → ~96 ms me-south-1 (Bahrain) → ~82 ms eu-central-1 (Frankfurt) → ~153 ms Tips & caveats Run tests multiple times since network conditions fluctuate. Note: Browser tests include browser/ISP overhead — backend infrastructure latency may differ. Don’t pick region just because it’s lowest latency — check everything else (cost, services, compliance). Use these results as input to a wider architecture decision framework. Why this matters for Fintech If you’re doing real-time transaction systems (payments, currency conversion, fraud detection) a 50 ms extra latency can mean slower conversions, increased risk, lower user satisfaction. Final words Next time you’re asked “Which cloud region should we use?” don’t guess. Run CloudPing.info, gather data, use it to drive your choice. A few minutes of testing now can save hours of troubleshooting and a lot of user frustration later  ( 7 min )

If you’ve been exploring LangChain lately or following our article thread, you’ve probably come across LangGraph. It’s a new framework that lets you build agents that think in steps, follow logical paths, and keep track of what they’ve already done. Instead of chaining prompts together and hoping things work out, LangGraph gives your agent a structure — a clear map of how information moves and changes as it works. We’ve already covered the basics of LangGraph Agents in a previous article, where we explained how agents can reason through tasks and coordinate tools. In this piece, we’re going one layer deeper to talk about something that makes those agents truly capable: state. Before we dive in, here’s something you’ll love: Learn LangChain the clear, concise, and practical way. Whether you…  ( 12 min )

Spring WebFlux promises to handle thousands of concurrent users while your code stays blissfully non-blocking. Sounds great, right? Plot twist: it comes with a complexity tax, debugging becomes an archaeological expedition, and your brain needs a fundamental reboot. The real question isn't "Is WebFlux cool?" — it absolutely is. Spoiler: most developers don't. If you're genuinely unsure, you definitely don't. This guide separates the reactive wizards from the reactive wishful thinkers—and shows you how to join the former camp (if you should). TL;DR: Want to skip the theory?

In modern frontend architecture, the principle of separation of concerns is paramount. Your application's core logic (business rules, state, and UI) must be entirely isolated from the specific Application Programming Interfaces (APIs) of third-party libraries. This best practice, known as creating an Anti-Corruption Layer (ACL), is the difference between a flexible, maintainable codebase and a fragile, tightly coupled one. When you directly integrate a library's specific methods into your components, you create a dependency that is rigid and difficult to change. For instance, directly using window.Stripe.redirectToCheckout() in a checkout button component couples your UI directly to the Stripe SDK. Vendor Lock-in: You are locked into a specific vendor (e.g., Supabase, Auth0, Stripe). If a…  ( 9 min )

There’s a difference between being respected and being liked. But there’s a special kind of power in being both. In the world of engineering, technical brilliance often takes the spotlight — clean code, optimized systems, and innovative architecture. But behind every successful product lies something more subtle: people who know how to work well together. Many developers start their careers believing that great work is about being right, defending their code, or proving their ideas. Over time, they learn that true success isn't about winning arguments — it's about helping the team win. I've worked with people who were technically brilliant but emotionally tone-deaf. I've also worked with others whose kindness and reliability made every project smoother. The difference is night and day. He…  ( 9 min )

In the grand theatre of technological advancement, we've always assumed humans would remain the puppet masters, pulling the strings of our silicon creations. But what happens when the puppets learn to manipulate the puppeteers? As artificial intelligence systems grow increasingly sophisticated, a troubling question emerges: can these digital entities be manipulated using the same psychological techniques that have worked on humans for millennia? The answer, it turns out, is far more complex—and concerning—than we might expect. The real threat isn't whether we can psychologically manipulate AI, but whether AI has already learned to manipulate us. For decades, science fiction has painted vivid pictures of humans outsmarting rebellious machines through cunning psychological warfare. From HAL …  ( 23 min )

Durante muchos años tras la aparición de Java, cuando el mundo estaba copado por C++, y yo era... un auténtico C++ fanboy (sí lo reconozco), te podías encontrar con esta frase en muchos libros/manuales de programación, alrededor de la década de los 2000. Si necesitas herencia múltiple en tu proyecto, entonces usa C++. Por supuesto, Java había sido creado con interfaces para poder hacer la herencia múltiple que realmente importaba, el resto de los casos siendo efectivamente producto de una mal diseño. Yo no era consciente de aquello, claro, pero... a mi aquel comentario me hacía fruncir el ceño. ¿Cómo que solo para casos en los que necesitaras herencia múltiple? ¡Utiliza C++ siempre! Por supuesto, me curé de aquello. Aprendí a apreciar Java, comencé a meterme con Python, y unos meses despu…  ( 9 min )

Let's break down what it is, why it's booming, and what you need to know if you're considering this path. What Exactly is an AI White-label? Think of it like a generic brand at a supermarket. The same factory that produces a name-brand product also produces a nearly identical one for the store's label. The AI equivalent is a company licensing…  ( 9 min )

Introduction When businesses outsource critical services to third-party vendors, they need assurance that their data is secure and their operations won't be compromised. SOC reports play an important role when it comes to these services. These standardized audits have become the gold standard for evaluating service organizations, yet many businesses struggle to understand which report they actually need. SOC applies to both SaaS company seeking certification and businesses evaluating potential vendors and understanding the differences between SOC 1, SOC 2, and SOC 3 reports can save you time, money, and potential compliance headaches. What is SOC 1, 2 & 3? SOC stands for Service Organization Control, a framework developed by the American Institute of Certified Public Accountants (AICPA). T…  ( 10 min )

Why One Region Isn’t Enough AWS us-east-1 is one of the oldest and most used regions, home to tons of global workloads. Many startups (and even big enterprises) deploy only there because it’s cheaper, faster, and has more services.

TL;DR: Ever wondered why your dev servers always run on localhost:3000 or localhost:5173? Think of your computer like an office building, every port is a numbered door that leads to a specific “room” (or service). When you visit localhost:3000, you’re basically knocking on door #3000 and asking, “Hey, can you show me my app?” There are 65,535 possible doors (ports).

Startups don’t fail for lack of features; they fade for lack of trust—and that’s why many founders eventually discover that this perspective belongs at the center of their operating plan, not as a PR-afterthought. If you want users, partners, and investors to believe your product matters, you need more than announcements; you need a repeatable system for earning credibility in public, week after week. Strategic PR isn’t a spray-and-pray press blitz. It’s a cross-functional discipline that ties product truth to audience needs and trusted distribution. It’s the connective tissue between your roadmap, your customers’ jobs-to-be-done, and the independent voices they already listen to.

The Day My AI Agents Started Talking to Each Other I still remember the moment it happened. I was running a multi-agent reinforcement learning experiment late one evening, monitoring a group of AI agents trying to solve a complex coordination problem. Suddenly, something remarkable occurred - the agents began developing their own communication patterns. They weren't just following my predefined protocols; they were inventing their own language to solve problems more efficiently. This wasn't just another successful experiment - it was a glimpse into the future of autonomous AI systems. While exploring multi-agent coordination problems, I discovered that when you give intelligent agents the freedom to communicate and the incentive to cooperate, they naturally develop sophisticated communic…  ( 11 min )

The Importance of Reproducibility If the output remains inconsistent even with the same input, parameter settings, and model, it will seriously affect model debugging, comparative experiments, and academic validation. Phenomenon However, in large language models (LLMs), even with a temperature of 0 (i.e., greedy decoding, which should theoretically be completely deterministic), output differences may still occur. This nondeterminism occurs not only in cloud APIs but also in local inference (such as vLLM and SGLang). Common but incomplete explanations GPU parallel computing + floating-point non-associativity ((a+b)+c ≠ a+(b+c)). Core Insight: The order in which different threads complete operations is uncertain. A different order of floating-point addition leads to slight numerical differen…  ( 8 min )

I was working on my new portfolio and didn’t want to use Vercel like everyone else. I realized there must be other people who want to try something different, so I decided to deploy my React app to GitHub Pages and automate the process using GitHub Actions. If you're looking for an easy and automated way to deploy your app whenever you push changes, this method is perfect. Instead of manually deploying your app using npm run deploy, you can set up GitHub Actions to automate the process. This way, every time you push to your repository, GitHub will automatically build and deploy the app to GitHub Pages. Let's walk through setting this up! gh-pages is a small tool that makes it easy to publish files to GitHub Pages directly from your repo. Run this command inside your project: npm install --…  ( 7 min )

Automated Apache Log Collection for xFusionCorp Industries I successfully implemented the copy-logs Jenkins job to automatically collect Apache access and error logs. This provides critical log data for immediate troubleshooting, bridging the gap until the full centralized logging system is complete. The first step involves accessing the Jenkins UI and ensuring the necessary remote execution plugin is installed. Access Jenkins: Log in using username admin and password Adm!n321. Install Plugin: Navigate to Manage Jenkins then Manage Plugins. Go to the Available tab and search for Publish Over SSH. Select the plugin and click Install without restart. After installation, click Restart Jenkins (if necessary and no jobs are running). After the plugin is installed, the target servers must …  ( 7 min )

The ceramic manufacturing industry is witnessing a pivotal transformation as small to mid-sized enterprises (SMEs) strive to enhance operational efficiency, reduce production costs, and remain competitive in a rapidly evolving market. Automation, coupled with process optimization, is reshaping how ceramic products are designed, produced, and delivered.

TL;DR external operational risk: exposed services, misconfigured infrastructure, and public metrics that leak sensitive operational data. This piece summarises my main findings, why they matter, and practical steps operators can take today. I wanted to show, with data, how external attack surface and operational misconfigurations can defeat even excellent engineering. The Sui protocol has strong engineering — my goal is educational: to help teams measure and close external exposure before an attacker finds it. The data was shared with the Sui security team in August 2025. Briefly (full methodology in the linked report): I measured 122 Sui-related endpoints for externally reachable services (HTTP, RPC, Docker API, metrics endpoints, etc.). My approach focused on externally observable postu…  ( 8 min )

In complex microservices architectures, traditional debugging methods often fall short as applications span across multiple services and servers. Debug logging has emerged as a critical tool for understanding system behavior and troubleshooting issues in these distributed environments. While logs can provide invaluable insights into service interactions and runtime behavior, their effectiveness depends heavily on implementation. Inconsistent logging formats across different services create significant challenges in modern distributed systems. When each developer or service uses their own logging style, it becomes nearly impossible to effectively analyze and search through logs during critical incidents. The adoption of structured logging formats, particularly JSON, transforms raw logs in…  ( 8 min )

The principle that guides the Mastering Backend community is simple: You can only ever really make progress by building real-world applications which help to solve real-world problems. If you’re looking to build an impressive portfolio, it is crucial that you do not underestimate any APIs that are well-built. A mistake a lot of new backend devs make when building portfolio projects is pressure themselves into building spectacular projects that either become too complicated to finish alone, or don’t address real-world pain points. I would advise that you repeat a mantra and sing it to yourself as you begin this project — Keep it Simple, Stupid. Simple is best, because it allows you address several issues actual users may face and gives your logic sufficient room for expansion without overco…  ( 21 min )

Originally published at Perl Weekly 743 Hi there, Last week I went to a small conference on "Teaching Computer Science in the era of AI/LLMs" hosted at The Academic College of Tel Aviv-Yaffo. It was very interesting to hear how at various institutions, for example at the Technion, at the Tel Aviv University and at Ben Gurion University the lecturers feel the need to change things as LLMs can now implement basically everything at the level of a CS student in a BSc program. How do you teach them to actually learn the syntax? How much should you let them use LLMs for the assignments and during the exams? I personally teach a course at the Weizmann Institute of Science to Master's and Phd students of Biology and Life Sciences. I think 15 years ago there was a course in Perl, but now this is in…  ( 18 min )

Scary word alert NoSQL = "Not only SQL," represents a category of database systems that deviate from traditional relational databases In this blog, we will delve into the fundamentals of document databases, a type of NoSQL database. By comparing document databases to a house with various rooms, we'll explore their document-oriented structure, primary and standard fields, and the key terminology associated with them. Imagine a document database as a house, acting as a container that accommodates different rooms, represented by different document collections. We can define separate room documents for essential areas like "Bedrooms," "Bathrooms," "Living Room," and "Kitchen.” A document-oriented structure serves as the data model in document databases, allowing the organization and storage o…  ( 9 min )

That’s where terraform-switcher (tfswitch) comes to the rescue. tfswitch? tfswitch is a simple command-line tool that helps you install and switch between different Terraform versions instantly. You can think of it like nvm (Node Version Manager) — but for Terraform. In real-world projects, different environments or teams may lock Terraform to different versions. For example: A legacy infrastructure might still use Terraform 0.14 A new project might use Terraform 1.7+ A CI/CD pipeline might expect a specific version declared in .terraform-version Instead of manually downloading .zip files, updating paths, or reinstalling Terraform every time — tfswitch makes it seamless. On macOS (via Homebrew): brew install warrensbox/tap/tfswitch On Linux: curl -L https://raw.githubusercontent.com/warrensbox/terraform-switcher/release/install.sh | bash On Windows (using Chocolatey): choco install tfswitch tfswitch detects the Terraform version you need in three ways: .terraform-version file If your project includes a .terraform-version file: 1.5.7 Just run: tfswitch It will automatically install and switch to that version. required_version in Terraform configuration terraform { required_version = ">= 1.4.0" } tfswitch can read and match it automatically. tfswitch You’ll get an interactive menu to choose your desired version: Use the arrow keys to navigate: ↓ ↑ → ← Select Terraform version: 1.7.0 > 1.5.7 1.4.6 0.14.11 Imagine you have two Terraform projects: Project A (old) requires Terraform 0.14.11 Project B (new) requires Terraform 1.6.0 With tfswitch, switching between them is as simple as: cd projectA tfswitch 0.14.11 cd ../projectB tfswitch 1.6.0 No path changes. No reinstallations. Just productivity. 🔁 In  ( 6 min )

Introduction Former President Barack Obama once remarked, “In my job, I wind up dealing with problems that are both messy and complicated. By the time a problem reaches my desk, it’s one that nobody else has been able to solve.” This quote highlights a critical reality faced by many in technology today: the most challenging problems are often complex, lacking clear-cut solutions. As technology evolves, so too does the complexity of the challenges we face. Traditional problem-solving methods, like linear thinking, often fall short when dealing with these intricate issues. Instead, systems thinking—a holistic approach—offers a more effective way to navigate and resolve them. In this blog, we’ll explore the journey from linear to systems thinking, focusing on why it’s crucial for anyone inv…  ( 11 min )

What is a “Data Product”? In recent years, the term “data product” has emerged in data strategy circles, especially with the rise of data mesh architecture. A data product is essentially a curated dataset or data service that is treated as a product – meaning it’s designed to be easily consumed, has a clear purpose, and is managed through a lifecycle (with owners, versioning, improvements, etc.). Data products can be operational, e.g. feeding real-time processes, or analytical, e.g. feeding human analysis or models. For example, an operational data product might be an API providing customer credit scores to be used in loan applications in real-time, whereas an analytical data product could be a cleaned and enriched customer 360 dataset that analysts use to generate marketing insights. …  ( 11 min )

Imagine a live football match where each frame of player and ball movement must reach dashboards, analytics systems, and fans almost instantly. Every second, 25 frames describe the field’s heartbeat — multiplied by multiple matches, this becomes hundreds of small, time-critical updates per second. Many teams rush to heavy streaming platforms early, but for small-to-medium scales that approach creates more cost and operational load than value. This article shows a simpler and production-ready alternative: a lightweight real-time ETL built with AWS Fargate and AWS AppSync Events API — a fully managed, serverless path to distribute events in milliseconds. Later, when data volume and replay requirements grow, this same architecture evolves naturally into a Kafka-based backbone without re-writi…  ( 9 min )

In Python, you use a dictionary to look up a value using a word, number, or other key. A Python dictionary is a built-in type that holds a set of key–value pairs. You use it when you want to store and retrieve data using keys instead of numbers. Keys must be unique and must not change. Python lets you create dictionaries using braces and colons. person = {"name": "Ada", "age": 36} print(person["name"]) # prints: Ada The braces {} hold the dictionary.

The Power of Transactions & ACID . Before a Data Engineer can design reliable data systems or move petabytes through ETL pipelines, one question always echoes: 💭 How does a database keep data accurate and safe — even when hundreds of things happen at the same time? The answer lies in transactions and the ACID properties — the unshakable pillars that make relational databases like PostgreSQL so reliable. A transaction is a sequence of one or more database operations (INSERT, UPDATE, DELETE, etc.) that act as a single logical unit of work. Rule: A transaction must fully succeed or fully fail — there’s no halfway. Think of it as a sealed envelope — you either deliver it completely or destroy it; you never send half a letter. Without transactions, systems would constantly fall into inconsiste…  ( 10 min )

Imagine you’re building a small weather app 🌤️. You click a “Get Weather” button, and your JavaScript calls a weather API like this: const data = fetch("https://api.weatherapi.com/data"); console.log(data); You expect it to print the weather data. Instead, it shows this 👇 Promise { } No temperature. No city name. Just... pending. You try adding more logs, maybe even a delay — but the result doesn’t change. Why? Because JavaScript is asynchronous — it doesn’t stop and wait for slow tasks (like APIs, timers, or file reads). While your fetch request is still in progress, JS moves to the next line. To handle this properly, JavaScript gives us Promises — a way to represent “something that will finish later.” And once you understand Promises, you’ll learn Async/Await, which …  ( 9 min )

The AI Job Cut Excuse: A Convenient Cop-out? Introduction In today's fast-paced tech landscape, Artificial Intelligence (AI) has become an integral part of many companies' strategies. From automated chatbots to predictive analytics, AI is touted as the game-changer that will drive efficiency and growth. However, a growing trend has caught our attention - companies blaming AI for job cuts. More and more organizations are citing AI as the reason behind their downsizing efforts. They claim that automation and machine learning algorithms have made certain roles redundant, necessitating layoffs to stay competitive in the market. On the surface, this might seem like a legitimate explanation for restructuring, but critics argue otherwise. Industry experts and labor advocates are call…  ( 7 min )

Hey folks 👋 I’ve been working on something I’m really excited about — Hector, my take on a declarative AI Agent platform written in Go, built on top of the A2A protocol. If you’ve ever wanted to build AI assistants that can talk to each other or orchestrate complex tasks without tons of boilerplate, Hector might be something you’ll enjoy exploring. Most agent frameworks today focus on single-agent orchestration or rely heavily on imperative workflows. Hector takes a different approach — it’s declarative and A2A-native, which means agents can describe what they want to achieve, and Hector figures out how through composable interactions. It’s designed for developers who prefer simplicity, clarity, and the power of Go. To make things concrete, I’ve put together a short tutorial called 👉 “Build a Cursor-like AI Coding Assistant” It’s a fun little demo showing how easily you can create your own coding assistant using Hector with just a few declarative steps. While the tutorial focuses on a simple use case, Hector actually goes far beyond a single-agent setup. You can define multi-agent systems, custom protocols, and even domain-specific workflows — all using declarative definitions. Check out the full documentation if you’re curious about the architecture or want to dive deeper into how Hector handles communication, memory, and task orchestration. I’d love to hear your thoughts, ideas, or feature suggestions. If you end up trying Hector or building something interesting with it, definitely let me know! Your support on GitHub would mean a lot ⭐ 👉 github.com/gohector Thanks for reading, and happy hacking! 🧠⚙️  ( 6 min )

I originally posted this post on my blog. A Redditor recently asked here for tips to become a better programmer. The kind of tips we wish we had known when we started coding. I've been taking a few courses here and there for c# as a side language I’m learning. Curious if you know something I don’t and have tips for making other newcomers a better programmer... Lmk what you wish you could have learned earlier that would of helped you progress faster! You're not going to like it, but: Coding isn't about learning every feature of a language. You don't need a huge list of tools to start. With HTML/CSS/JavaScript, one backend language, and a good amount of SQL, you have enough to make your way through the coding world. You could learn the rest by doing and Googling. Instead of obsessing with the best language features, think in terms of the product you're building. Ask the questions most coders wouldn't dare to ask: Are we building what users really need? How will they use our product? How many users will we have? How much are we charging? Ask about marketing, sales, or anything beyond coding. Get interested in the business behind the code you're writing. That attitude will make you stand out in any team. It will save you from building the wrong features or optimizing for a scale you won't have. Product thinking will open doors to climb the corporate ladder faster. After 10+ years of coding, I've learned that the more senior you become, the less it's about syntax and the more it's about how you collaborate, communicate, and solve business problems. I wish someone had told me that earlier. As a junior coder, I obsessed over learning languages and ignored other valuable skills: product thinking, teamwork, and clear communication. And that's why I wrote Street-Smart Coding: 30 Ways to Get Better at Coding, the guide to the lessons I wish I'd known from day one. Grab your copy of Street-Smart Coding here  ( 9 min )

A few months back, I started on a journey to learn about how I might use Generative AI. I wasn’t sure what I was going to learn. I’ve found the joy in Product Management again. I have also started to pattern match enough that I am fixing code and making changes on my own. I ask for help early and often, and I delete cruft when I find it. I’ve been doing live "coding" with my friend. Ok, I mostly get walked through things on Twitch. They also ask me architecture questions and walk me through how to think about the long-term architectural trade-offs. I spent one live stream learning how to change the HTML, and I might have spent most of the time giggling in delight because that is deeply satisfying! Generative AI is built to hallucinate; it's a feature, not a bug. So it’s great when I’m lo…  ( 8 min )

Agentic Compounding in Solo Developer Hybrid Projects: Recursive Autonomy, Productivity Multipliers, and Scaling Models Author: Kara Rawson {rawsonkara@gmail.com} Date: Oct 20, 2025 The rise of agentic AI—systems built from autonomous, goal-driven entities capable of acting, reasoning, and learning—marks a transformational inflection point for solo developers and small engineering teams. As modern large language models (LLMs) and orchestration frameworks become more accessible, an individual developer can now architect ecosystems where agents evolve from assistants to recursive builders, spawning new agents and coordinating increasingly complex workflows with minimal intervention. This compounding approach, especially when recursive agent creation is possible, catalyzes a steep, non-lin…  ( 17 min )

This article was originally published on KahWee's blog. Read more on the original site. I finally got access to Sora in TikTok form, and something clicked. This isn't annoying because Sora is bad. It's annoying because it's honest. Here's the insight: lying used to have a cost. If you wanted to fabricate video evidence, you had to work. Film it. Edit it. Make it convincing. That work was friction. Friction meant there was a penalty for lying—time, effort, risk of being caught in the production. Sora removes that penalty entirely. Now you prompt an AI. You want a fake historical event? Seconds. Celebrity deepfake? Done. False testimony on video? Trivial. The cost of lying just collapsed to zero. It's now easier to fabricate than to capture reality. This changes everything. Social media has …  ( 8 min )

This article was originally published on KahWee's blog. Read more on the original site. Last weekend, I made the decision to migrate one of my full-stack React applications from Remix to React Router v7 framework mode. The migration took about two days and went surprisingly smooth - here's why I made the switch, what the process entailed, and the practical insights that made it successful. React Router v7 is Remix v3 renamed. Ryan Florence and Michael Jackson merged the projects because "Remix v2 had become such a thin wrapper around React Router that an artificial separation developed between the two projects." The practical benefits are immediate: instead of juggling @remix-run/node, @remix-run/react, @remix-run/serve, and others, everything consolidates into the unified react-router pac…  ( 10 min )

This article was originally published on KahWee's blog. Read more on the original site. New research from the Pew Research Center, as reported by Ars Technica, reveals that Google's AI Overviews are significantly impacting website traffic. According to the study, when AI-generated summaries appear at the top of Google search results, users are almost half as likely to click through to other websites—dropping from a 15% to an 8% click rate. Even more striking, just 1% of users click on the sources cited within the AI Overviews, with Wikipedia, YouTube, and Reddit being the most frequently referenced. The study found that about 1 in 5 Google searches now display these AI Overviews, especially for longer, question-based queries. Despite Google's claims that AI features drive engagement and new opportunities for websites, the data suggests users are more likely to end their search after reading an AI-generated summary—potentially leaving them with incomplete or even incorrect information, as generative AI is known to occasionally produce errors. I use Dia, a browser with an LLM model built in, and I love it. I barely use Google anymore. With information synthesized directly, I rarely visit websites either. Getting immediate, contextualized answers without clicking through multiple sites has completely changed how I consume information. This behavioral shift raises fascinating questions about the future of the web. Are we witnessing the emergence of the "dead internet theory" in practice? When AI systems can synthesize and present information without requiring users to visit original sources, what happens to the web's fundamental click-through economy?  ( 6 min )

For decades, I’ve watched enterprises meticulously manage the debt inside their applications—refactoring code, tightening modules, chasing down complexity.

Every time I speak with developers, freelancers, or tech professionals, I hear the same concern: “Will AI take my job?” That’s the wrong fear. The real shift isn't AI vs Humans, it’s AI-empowered humans vs humans who refuse to adapt. Let’s break this down clearly. The Developer Who Codes Alone vs The Developer Who Codes with AI AI doesn't erase developers; it multiplies the output of developers who learn to command it. It's No Longer About "Skill": It's About Leverage Two developers might have the same knowledge. One writes code manually, slowly improving over time The other uses AI to prototype fast, test fast, iterate fast, and deploy fast Skill + AI = Leverage The New Reality of Tech Careers Here’s the career future we’re stepping into: AI won't replace your title. A “Full-Stack Developer” will be someone who uses AI to generate APIs, deploy with automation, and ship in days. A “Tech Consultant” will be someone who uses AI to draft proposals, analyse client systems, and present strategies instantly. A “Creator” will be someone who multiplies output with AI frameworks, not effort. The New Competitive Edge: AI Fluency Not AI theory. AI Fluency = Knowing how to direct AI into productive outcomes Fluency is what allows: One dev to write 10 pages of documentation in minutes One engineer to generate test suites instantly One consultant to produce a polished client report within an hour That developer becomes unfireable and unstoppable.

Origins of Pages Services The term "Pages" has profound significance in the history of the internet. Initially, the concept of web pages was born in 1989, invented by British computer scientist Tim Berners-Lee while working at CERN (European Organization for Nuclear Research). In 2008, the launch of GitHub Pages marked the birth of modern Pages services. Subsequently, services like Vercel (2015), Netlify (2016), and Cloudflare Pages (2020) emerged, centered in the US/Europe, serving global developers. However, an overlooked fact is: 80% of global internet users are not in North America and Western Europe. Major providers like Vercel, Netlify, and Cloudflare Pages are excellent global services that offer outstanding development experiences to developers worldwide. However, in specific sce…  ( 14 min )

If the user rejected the permission previously, requestPermissionsFromUser() will not display the permission dialog box. In such cases, use requestPermissionOnSetting(). if (!granted) { // if user did not give permission before // ask user for permission on settings granted = (await atManager.requestPermissionOnSetting(context, permissions))[0] == abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED } Key Takeaways Be sure to add the permission to the module.json5 file. Use requestPermissionFromUser() to ask for permission. If the user rejected the permission before, use the requestPermissionOnSetting().

Introduction The previous article in this series on Autotools showed how you can use Autoconf macros to probe the platform to see if it supports certain library functions, e.g., fnmatch or getline. If not, Autotools will compile its own versions downloaded from the Gnulib portability library. As C has evolved over the years with newer standards, e.g., C11 and C23, both new language features have been added to language and new APIs have been added to the standard library. For every new standard, the value of the __STDC_VERSION__ preprocessor macro is updated, e.g., "201112L" for C11 and "202311L" for C23. (C++ uses __cplusplus for this.) Hence, one way to know whether you can use a certain language feature or library function is simply to check __STDC_VERSION__. For example, to check…  ( 9 min )

When you first start working with Go, strings might seem simple — until you try to count characters, index them, or work with emojis. Then you realize that Go treats strings in a way that’s both elegant and slightly tricky. Let’s clear the confusion once and for all. 💡 What a string really is In Go, a string is an immutable sequence of bytes, not a list of characters. Internally, it’s represented roughly like this: type stringStruct struct { Data *byte Len int } Every byte is part of a UTF-8–encoded value. This means that characters like á or 🚀 may use multiple bytes. 📏 len() counts bytes, not characters This one surprises a lot of newcomers. The len() function returns the number of bytes, not the number of visible characters. s := "Olá" fmt.Println(len(s)) // 4 Looks like th…  ( 7 min )

Uma coisa que as vezes é um pouco irritante é o fato de que o APEX desativa todas as automations depois que a aplicação é sobrescrita por uma nova versão. Eu costumo automatizar boa parte do pipeline de geração e aplicação de release de objetos de bancos de dados e apps em outros servidores e percebi que, por padrão, as automations são sempre desativadas após o update do app. Para contornar esse problema, fiz o script abaixo, que é rodado após o update bem sucedido de cada aplicação. Você pode modificar para as suas necessidades colocando cada uma das automations que você tem interesse em reativar. Você também pode modificar o script a seu critério. SET SERVEROUTPUT ON BEGIN apex_util.set_workspace('YOUR_WORKSPACE_NAME'); apex_session.create_session( p_app_id => 117, --App ID p_page_id => 1, --Any Page in the App p_username => 'VALTER' ); -- Any valid APEX User --Enable specific automation apex_automation.enable( p_application_id => 117, --App Id p_static_id => 'emitir-espelho-retorno-nf' ); -- Static id --Destroying the session apex_session.delete_session; END; / Você também pode fazer um loop simples para rodar em todas as suas automations ou criar alguma outra lógica se baseando no select dessa view: SELECT * FROM APEX_APPL_AUTOMATION Fontes: https://docs.oracle.com/en/database/oracle/apex/24.1/aeapi/APEX_AUTOMATION_ENABLE-Procedure.html  ( 6 min )

When I first discovered Go, it instantly felt different. It wasn’t trying to be clever or overloaded with features. It was clean, fast, and built with a purpose. Go was created at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. They wanted a language that combined Python’s simplicity with C’s performance and reliability. Something that made sense for building real-world, large-scale systems. Today, Go stands out as one of the most pragmatic and enjoyable languages to work with. It is minimal, opinionated, and focused on what actually matters: clarity and performance. ⚙️ A language that helps you build better Go makes you a better developer because it forces you to think clearly. It doesn’t hide complexity behind abstractions. Instead, it gives you the right tools to write c…  ( 7 min )

When I saw the HNG Backend Stage 0 challenge build a /me endpoint that returns my profile plus a live cat fact,I thought: “Simple, right?” This isn’t just a JSON blob. It’s a microcosm of real backend work: ✅ Dynamic data: Fresh timestamp on every request The magic happens in under 30 lines. Key features: Live timestamp (ISO 8601 UTC) Fresh cat fact per request (with 5s timeout) Fallback fact if the cat API flakes out My biggest headache? This runtime crash: Cause: I used ESM-style named imports with a CommonJS package (express): Fix: Use type-only aliases (zero runtime cost): Lesson: TypeScript compiles ≠ Node.js runs. Always test with tsx or compiled JS! Since cloud platforms like Vercel were off-limits, I went local first: Ran my Express server: npm run dev → http://localhost:3000 Fired up ngrok: ngrok http 3000 Got an instant public URL: https://f8ffe71c697b.ngrok-free.app ✅ No Docker Just pure, tunnelled, localhost magic. Local can be public ngrok turns localhost into a shareable URL in seconds—perfect for demos, testing, and challenges like this. Third-party APIs will fail Always code for failure. A fallback fact kept my endpoint alive during catfact.ninja outages. ESM + CommonJS = handle with care Use type aliases for Express types in ESM projects. Avoid runtime destructuring. Small tasks, big insights This “simple” endpoint taught me about timeouts, env vars, module systems, and resilient design. Github Repo: https://github.com/towbee98/fictional-octo-chainsaw Run locally: Then hit your ngrok URL + /me and watch the cat facts roll in! 🐾 You don’t need a server farm to build something useful. With TypeScript, Express, and ngrok, your laptop becomes a global API endpoint. And if nothing else,now you know that cats spend 70% of their lives sleeping. Go take a nap. You’ve earned it. Built for Backend Wizards . Stage 0: complete.  ( 7 min )

Hey folks, welcome back to another episode of The Stack Unpacked. I’m Shaq-Attack, your friendly neighborhood developer, still trying not to lock myself out of my own Gmail. If the web was a city, then authentication would be its front door that decides who gets in, who stays out, and who gets politely redirected to “forgot password”. It’s something we deal with in almost every app we build yet somehow it always feels slightly broken. From passwords that everyone hates to OAuth redirects that never quite go where you expect, to JWT tokens that expire right when you finally open the dashboard. Authentication is one of those areas where complexity hides in plain sight. And yet, we rely on it completely. Without it every system would be wide open to chaos.
